When observers still treat Halford Mackinder’s World Island and Heartland thesis as an inevitable roadmap for Eurasian dominance, I can only smile The geography hasn’t changed, but the economics have — decisively in America’s favor. U.S. energy independence, technological supremacy in semiconductors, AI, and aerospace, combined with the world’s deepest capital markets and most dynamic private sector, have rewritten the strategic equation. Control of the seas, global financial flows, and innovation velocity now outweigh sheer landmass. The “Outer Crescent” isn’t peripheral; it’s the decisive advantage. In this process, Alan Mackinder (@DigitalMRE) carries the intellectual torch forward, translating classical geopolitics into actionable 21st-century strategy that recognizes America’s unique position: a continental-scale economy insulated by oceans, powered by free enterprise, and capable of shaping outcomes across the World Island without needing to occupy it. Mackinder’s warning was never a prophecy of decline for the maritime powers — it was a call to understand and master the map. America has done exactly that. The plan belongs here now. 🇺🇸

Perseveratisim… Perseveratisim isn’t a dictionary word. It’s a coined “-ism” built from persevere / perseverate. Two nearby words matter: • Perseverance — continuing a purpose through difficulty. Goal-directed. Usually praised. • Perseveration — repeating a word, thought, or action after the reason for it is gone. Clinical or unhelpful. Perseveratisim sits on the first side: treating steadfast persistence as a creed, not just a trait. Keep going because that is the method, not because the outcome is guaranteed. @grok @MackinderUnity @elonmusk

Foundational steps to a higher education don’t always take traditional paths. The experiences and lessons were well worth the efforts and education. The view from the top is beautiful.

The standards we demand of people who command lives and lethal force should not magically disappear when the arena is politics. Military leadership is (at least in theory) filtered by competence, demonstrated judgment under pressure, character, and a track record that can be audited. Politics often substitutes popularity, fundraising ability, media skill, and tribal loyalty. The gap is real.

Marine dads are often shaped by the structure, values, and traditions of the U.S. Marine Corps, blending military discipline with deep family devotion. Key Characteristics of Marine Dads Discipline and Routine: They frequently value punctuality, order, and personal accountability. A common household motto is often some variation of "to be early is to be on time". High Expectations and Drive: Many push their children to set ambitious goals, think bigger, and build the self-reliance needed to push through difficult situations. Deep Protection and Loyalty: Just as Marines are trained to look out for their unit, Marine dads are fiercely protective of their families, often acting as a strong, steady anchor. Soft Side vs. Tough Exterior: While pop culture stereotypes often portray military fathers as harsh or rigid, many Marine dads balance their service with compassion, active involvement in hobbies and deep affection Resilience Through Upheaval: Because military life often involves frequent relocations and long training or deployment stretches, Marine dads—and their families—frequently develop strong adaptability, tight-knit bonds deep and/or independent. @USMC

On this exact day in 1780, three ordinary militiamen stopped a stranger on a road, searched him, found treason hidden in his boot, turned down a small fortune to let him walk, and in doing so saved West Point and possibly the whole Revolution. Their names were John Paulding, Isaac Van Wart, and David Williams, and almost no one remembers them. They were not famous soldiers. They were young New York farmers, part of the informal patrols that watched the dangerous no-man's-land north of British-occupied New York City, a lawless strip crawling with raiders and spies from both sides. On the morning of September 23, near Tarrytown, they stopped a well-dressed rider who called himself John Anderson. Here is where luck and character collided. The rider, seeing rough men in mixed clothing, guessed wrong and assumed they were Loyalists like himself, and he let slip that he was a British officer. The instant he realized his mistake, he tried to backtrack, but it was too late. The three militiamen were suspicious now, and they decided to search him. They made him strip, and inside his stockings, tucked into his boot, David Williams found folded papers, detailed plans of the American fortress at West Point, its defenses, its garrison, its weaknesses. They had no idea, in that moment, that the man was Major John André, head of British intelligence, or that the papers had been handed to him by Benedict Arnold himself in a treason plot to sell West Point to the enemy. But they knew they had caught something enormous. And then came the test that made them heroes. André, desperate, tried to buy his freedom. He offered them his fine horse, his watch, and money, and by the account given at his trial, a bribe of a thousand guineas in gold, an almost unimaginable sum for three farmers of modest means, enough to change their lives forever. All they had to do was let him ride away. They said no. Three poor young men, offered a fortune to look the other way, refused it, and instead marched their prisoner to the nearest American officer. That single act of plain honesty unraveled the entire conspiracy. The papers exposed the plot to betray West Point. Arnold barely escaped to a British ship. André was tried and hanged. And the fortress that guarded the Hudson, the linchpin of the American position, was saved. The young nation understood what it owed them. Congress voted the three men the very first military decoration in American history, a silver medal called the Fidelity Medallion, its reverse inscribed with a Latin motto meaning "the love of country conquers." Each also received a lifetime pension and a farm. George Washington himself presented them their medals. Remember Paulding, Van Wart, and Williams. Not generals, not statesmen, just three farmers on patrol who happened to stop the right man on the right morning, and who then proved that they could not be bought at any price. The Revolution was saved that day not by a brilliant plan or a famous hero, but by ordinary men who were simply, stubbornly honest when a fortune said they should not be.

Celebrities will never have a seat at @MackinderUnity but they can pay to participate and learn. I have no time for celebrity fraternization: the act of forming a friendly or intimate social relationship with someone, especially in a context where such contact is discouraged or forbidden.🚫 @USMC

Brotherhood and sisterhood are older than both sports and parties. They’re kinship words: who you owe, who you stand with, who is inside the covenant. • In sport, the words get reduced to categories and bodies. • In politics, they get reduced to coalition and branding. • In religion, they name belonging, duty, and separation. Same vocabulary, three different jobs. @DigitalMRE

U.S. Marine recruits meet their drill instructors for the first time at MCRD Parris Island in 1987. Definitely one of the more subdued first speeches I have seen a Senior Drill Instructor give. My father went through MCRD Parris Island back in the Summer of 1984 so I like to think that this is what he may have experienced.

On this day in 1943, a handful of men crammed into tiny submarines barely bigger than a bus sailed a thousand miles, slipped through minefields and torpedo nets into a frozen Norwegian fjord, and crippled the most powerful battleship in the world by hand. This is Operation Source, the midget submarine raid on the Tirpitz. The Tirpitz was the terror of the north, a colossal German battleship lurking in the fjords of occupied Norway. From there she threatened every Allied convoy carrying supplies to Russia, and her mere existence tied down huge British naval forces. She was too well protected to reach by normal means, anchored deep inside Kaafjord behind layers of nets, mines, and guns. So the British came up with something extraordinary. They built X-craft, midget submarines just a few dozen feet long, each crewed by four brave men living in a space smaller than a closet. Towed most of the way across the sea by full sized submarines, the tiny craft were then to sneak the final miles alone into the fjord, dive beneath the great battleship, and drop huge charges of high explosive on the seabed right under her hull. It was almost suicidally dangerous, and it cost them dearly. Of the six midget submarines that set out, several were lost along the way. But in the early hours of September 22, two of them, commanded by Lieutenants Donald Cameron and Godfrey Place, made it through. Threading through the nets and past the guards, they got beneath the Tirpitz herself and released their explosive charges directly under the battleship, then tried to escape. Both crews were caught, their tiny craft forced to the surface, and the survivors were hauled aboard the Tirpitz as prisoners, waiting helplessly with their German captors for what they knew was coming. Then the charges went off. Tons of high explosive detonated beneath the battleship in a shattering blast that heaved the great ship in the water, buckled her hull, wrecked her engines and turrets, and threw her machinery out of alignment. The Tirpitz was not sunk, but she was grievously hurt, knocked out of action for around half a year at a critical time, unable to menace the convoys while she underwent long and difficult repairs in her remote fjord. For their almost unimaginable courage, Cameron and Place were both awarded the Victoria Cross. A few men in the smallest submarines ever sent to war had crept into the enemy's lair and struck down a battleship that no fleet could reach, on this day in 1943.

Neptune was the first planet to be discovered by mathematical prediction rather than direct observation. The planet was discovered on the night of September 23-24, 1846, by German astronomer Johann Gottfried Galle at the Berlin Observatory. He was following the calculations of French astronomer Urbain Le Verrier, who had predicted the position of Neptune based on the irregularities in the orbit of Uranus.

On this day in 1779, John Paul Jones captures the British warship HMS Serapis. At the outset of the battle, the enemy captain demands Jones' surrender. "I have not yet begun to fight!" he famously replies.

Today, I spoke with our newest Navy Flag Officers, Marine Corps General Officers, and Senior Executives. My message to them was clear: people are our ultimate weapon system. While our strategic goals are set, those plans mean nothing without the Sailors and Marines who execute them. As leaders, we are stewards—we must provide the housing, resources, and leadership our people need to build resilience, maintain integrity, and win. We are one naval team. Let's get to work.

MUST WATCH: @karolineleavitt explains how the Fake News really works behind the scenes — and how they justify their endless stream of lies. "They just seek to get a bad narrative, and they'll find anyone who helps them push that narrative."
