Marc Wilson 84.6% (22-4) Goes without saying that Bachmeier is the only one of the top five to have faced a power-conference schedule.

Dès mon arrivée à New York, j’ai rencontré le président Donald Trump. Nous avons décidé d’agir ensemble pour résorber les tensions sur les marchés de l’énergie, en protégeant les infrastructures critiques au Moyen-Orient et la liberté de navigation dans le détroit d’Ormuz. Nous allons aussi mettre nos efforts en commun pour obtenir un moratoire sur les frappes contre les infrastructures énergétiques et contre les infrastructures civiles ukrainiennes. Les populations civiles doivent être protégées et nous devons engager au plus vite une négociation sérieuse sur les conditions de la paix entre la Russie et l’Ukraine.

🇯🇵 Japan Is Quietly Building A Very Different Military Over 2025-2026, Japan has been adding capabilities that would have been extraordinary for the country a decade ago. Japan began acquiring US Tomahawk cruise missiles, and in March 2026 the destroyer JS Chokai became the first Japanese warship to gain Tomahawk launch capability. At the same time, Japan is expanding its Type 12 stand off missiles, submarine launched missiles, JSM and JASSM weapons, while moving ahead with its own hypersonic missile program. Japan says early mass production of its hypersonic guided missile began in 2026. The buildup goes far beyond missiles. Japan is expanding its F-35A and F-35B fleet, upgrading F-15 fighters, strengthening Aegis equipped ships and missile defense, adding unmanned systems, electronic warfare capabilities, surveillance aircraft, submarines and other naval assets. Japan is also building a satellite constellation to improve the detection and tracking of targets for stand off weapons, with initial satellite launches beginning around the end of FY2025. And this transformation is backed by enormous spending, Japan’s FY2026 defense program allocates roughly ¥973 billion just for stand off defense capabilities, including upgraded Type 12 missiles, hypersonic weapons, HVGP, JSM, JASSM and Tomahawk related capabilities. This is not simply Japan buying more weapons. It is Japan building a long range, networked, fifth generation and increasingly multi domain military force.

China is building giant robot submarines meant to reach the U.S. West Coast. It's already testing them. Satellite imagery from geospatial intelligence firm Vantor shows a mothership under construction at a Shanghai shipyard, designed to carry uncrewed submarines the size of small warships. Two versions have already been tested in Hainan, one 35 meters long, one 45. That's six to eight times the size of the U.S. Navy's own largest uncrewed sub. China is the first country in the world to build full-size uncrewed submarines at all. A defense analyst tracking the program named the scenario directly: potential deployment off the U.S. West Coast during a period of heightened tension or conflict. This isn't a system built to blockade Taiwan. It's a system built for what comes after, keeping the U.S. Navy pinned down at home while China finishes what it started in the strait. Nobody has to guess what that tension would be about. Taiwan isn't the endgame here. It's the opening move. taiwannews.com.tw/news/64432…

Thank you, @marklevinshow. I saw David’s work in the first term. He’s a fine young man. It never ceases to amaze me how the legacy press will carelessly destroy a person’s reputation or career based solely on innuendo or speculation, merely in exchange for a few clicks from President Trump haters. Good on you for standing up for David.
President Trump was right to ban Politico from the White House. And I want to tell you why, and about a specific situation this morning involving my stepson, David Milstein. David is a young man who is about to get married in Israel in October. He works for Ambassador to Israel, Mike Huckabee. In the first Trump term, David worked for David Friedman, the former ambassador to Israel. David is earnest and, hard working. Today, on Yom Kippur, my family and I awakened to one of the most outrageous and disgusting hit pieces written by Politico's Adam Wren. And I must briefly respond to this character-assassination.. First, if David wasn't my stepson, I've no doubt he wouldn't be treated like this. Attacking him like Wren did this morning, weeks before his wedding and on Yom Kippur is truly contemptible. Second, David is not controversial. He does his job professionally, carrying out the administration's policies in his support position to Ambassador Huckabee. He has been accused of multiple lies over the last 17-months, including about a meeting with Pollard -- in which David had no role whatsoever but was asked to attend. And he has been targeted by some of the most reprehensible individuals on the Internet and elsewhere. Third, David did not "solicit cash gifts from Israeli citizens to celebrate his upcoming wedding." David was asked by family members, who live all over the world and throughout the country, about gifts for his upcoming wedding and if he was registered anywhere. David responded to requests by sending an email-message that there was no registration for gifts and suggested an alternative option. The email-message was intended for family and close friends but went to the larger email list of guests. As soon as he realized it went to the larger list, literally in less than 48-hours, he sent another email making clear he would not and could not accept gifts of any kind from the larger group. It is that simple. He was not soliciting cash gifts from Israelis, as Wren sought a hook for his story. Wren then went to cherry-picked anonymous sources to create an entirely false narrative and impression to promote a non-existent controversy about David's clearance, etc. It is a truly unconscionable thing to do, and he did it to further embellish his story, Wren also claims people are afraid of David because I'm his stepfather -- according to more anonymous sources. This is pathetic like the rest of his hit piece. I've been around a long time. I've dealt with the press for decades. This has to be the most appalling and dishonest story of all. Wren knows exactly what he's doing, and he's doing it to one of the most honorable and decent people I know -- my stepson -- who has more integrity in his pinky than Wren will ever have.

After JJ Spaun’s impressive victory at the BMW PGA Championship, he said he felt like he had something to prove and had “imposter syndrome” after winning the US Open in 2025: “I believe this year was a tough year for me because internally I was fighting all these expectations of being a worthy Major Champion. “I felt like I still had to prove to everyone that I wasn't a fluke and I wasn't some money-in-the-bottle Major Champion. You hear things about that, and it kind of eats inside a little bit. I put way too much pressure on myself to start the year. “But once I kind of stopped caring so much, I mean, I know it's easy to say that, I mean obviously but that was kind of mantra all last season. That's why I played so well. I was on the verge of losing my job in 2024 and then I backdoored it to keep it, and I was like, Oh, this is house money, I wasn't even supposed to be here in 2025. That sort of attitude, along with obviously skill and developing and playing good, that was a breakout year. “And then here we are back in January and I'm back to this ball of pressure and expectation and thinking I have to be this perfect golfer and to validate whatever I did in 2025. “Once I kind of let go of that and stopped caring what other people think or what the media thought of me, I started relaxing and playing better. Then I won in San Antonio, and then once I won in San Antonio, okay, I'm pretty content with everything I've done. If I were to die tomorrow, I'd feel like I have. “It was just getting over that hump of expectation and mindset that I had last year and I started playing better. Like this week, I didn't have a ton of expectation. I couldn't play the Tour because I woke up with a stiff neck and couldn't turn it. So I had two weeks to get ready for this and I did it. “Sometimes no expectation is the best thing to have.” In JJ’s last 2 seasons he’s won his first major, won again on the PGA Tour, won the DP World Tour’s flagship event and finished runner up to Rory McIlroy at The Players Championship. He’s definitely not an imposter, he’s a certified champion and he has nothing to prove to anyone. @DPWorldTour @BMWPGA
JJ Spaun birdied 4 of his last 5 holes for a final round 67 to win the BMW PGA Championship by 2 shots over Rory McIlroy, Adam Scott, Aaron Rai and Manuel Elvira. Elvira came to last needing a par for a playoff but finished a double bogey 7. It’s JJ’s maiden DP World Tour victory and he did it in the flagship event at Wentworth.

It is math not just policy driving @realDonaldTrump’s strategy. According to some of our best naval experts, America has a very lethal & effective “one war navy.” Allies in Europe, Canada & Asia take note now. “Paying your fair share” & “burden sharing” are not just slogans. It is no longer about doing what’s right by the American taxpayer by ending the free ride. Having a capable military & naval service is going to be the difference between you appeasing or surrendering to the communist Chinese, Russian imperialists & jihadists & your very freedom. The time for choosing is now. @ElbridgeColby @cdrsalamander @russvought @JerryHendrixII @johnkonrad @AlexGrayForOK @MarkCMontgomery @conswahoo cdrsalamander.substack.com/p…

Nothing to see here guys. If you comment on CCP-linked activity, they imply you’re “racist”. Better not to notice any of this! “Richard Dearlove, former head of MI5, explaining how China's influence ops in the UK led to deindustrialization and a precarious dependence on China.”
Two important essays were published this week on the theme that the climate movement is now a serious national security risk for the US and Europe. This one in Tablet magazine: tabletmag.com/sections/news/… is by 2 authors, one from the Hudson Inst in DC and the other a professor at the Naval Postgrad Academy in CA. They trace the links between China and the western Net Zero movement, which is partly financial, but works mostly through influence operations by which the CCP gains exemption from criticism by western green groups despite its own coal-intensive and slave labor-dependent growth strategy. This one: thegwpf.org/content/uploads/… is by Richard Dearlove, former head of MI5, explaining how China's influence ops in the UK led to deindustrialization and a precarious dependence on China; to the extent that the UK could not now reindustrialize or stabilize its electricity grid without seeking assistance from Beijing. Dearlove's paper raises the possibility that a security agency like MI5 saw a threat building but was unable to address it because of a perception that climate science forbids criticizing Net Zero and related measures. A question I think worth asking is whether western intelligence agencies have internalized the green Net Zero mindset thereby preventing them from challenging the climate alarmism so effectively weaponized by the CCP. And if they now want to start doing so, would they know how, or have the capacity to do so.

#Winning. 🇺🇸@AlexGrayForOK has been the most prescient commentator on the #Greenland issue for the past 2 years. He nails it again in this @WSJ oped. The deal is a geopolitical master stroke by @realDonaldTrump — totally secures USA’s national security interest in the territory and removes any friction in our alliance with the Danes and other Nordics. Announced as an unrelated item on the eve of Chairman Xi’s visit is professional and effective messaging by the White House. Well done, @POTUS. wsj.com/opinion/trump-scores…

To repeat, this is an enormous deal. Keep score on who downplays it or minimizes its importance. President Trump has secured part of the gateway to the Arctic —an unqualified big win. Those that won’t admit it will also have likely damned POTUS for straining relations with Denmark and NATO over elevating the topic from the start of his second term. Now that is behind the allies, the threats are identified and excluded, access guaranteed for Golden Dome facilities and any other basing needs. Sheesh TDS is a powerful drug.
BREAKING NEWS: I am pleased to announce that the United States of America has entered into an Agreement with The Kingdom of Denmark, and Greenland, that gives the United States permanent control over security, and all other needs, in Greenland, completely addressing ALL of our many U.S. concerns. There will be NO COST to the United States! At my direction, we worked with representatives of Denmark and Greenland to guarantee that the United States will FOREVER have the complete ability to do what is necessary in Greenland in order to secure and defend the security of Greenland, and the United States of America. Additionally, from now on, no U.S. adversary can EVER have a base in Greenland, have a military presence in Greenland, or make sensitive investments in Greenland, without our express written approval. For over 100 years, Presidents have known the strategic importance of Greenland, but NONE of them were able to do anything about it. I am proud to be the President that permanently and conclusively addressed this very important situation. This is an “Infinite Life” Agreement, there is no end! We are very honored and proud of what has just taken place, and everything agreed to today will be cherished by the American People. We will immediately begin the process of developing a large Military presence in the appropriate part of Greenland, of which there are many. We will work with the people of Greenland in its development and construction. This solution is a great one for the United States of America, Denmark, Greenland, and all of our Allies. We look forward to working with the wonderful people of Denmark and Greenland toward a magnificent future with respect to this large, and highly strategic, parcel of land. We will be very protective of it! This is a dream come true for the United States of America, one that is very important, historic, and special. Thank you for your attention to this matter! President DONALD J. TRUMP

The United States may be entering the most dangerous period since the defeat at Fredericksburg in 1862. It is clear that our will to survive is declining. The Iranian religious dictatorship continues to chant “death to America” and continues to work on its nuclear program and its missile systems. It is openly allied with Russia, Communist China and North Korea. The. Iranians have been targeting Americans and are openly trying to drive the United States out of the Region. The Democrats have become their allies and consistently vote for surrender when the choice comes up in the Congress. Some Republicans have become tired of the fight and the confusion and would accept a face saving defeat. The American people entered this fight with a clear understanding of what is at stake. According to America’s New Majority Project 55% believe the Iranians really mean it when they say death to America (62% of independents). Nearly two thirds of Americans (64%) believe the nuclear threat is real. The Iranian refusal to negotiate in good faith helps convince 60% that the nuclear threat from Iran is real. In fact 64% of the American people believe that a nuclear armed Iran could target American cities and kill millions. A series of Presidential Oval Office addresses laying out the 47 year history of Iran attacking Americans, killing Americans, supporting terrorist groups to kill American and working consistently to build weapons to bring “death to America” would solidify support for an all out effort to replace the religiously inspired dictatorship which has proven again and again that it can take a tremendous amount of punishment and continue to work toward destroying America. We have to either defeat the Iranian dictatorship or accept a willingness to coexist with Iranian nuclear weapons and missiles capable of destroying our citizens and killing millions. We are at a crossroads and there is not a third choice.
