The Chuds found this so I'll point out what's blaringly obvious to anyone who loves this movie and has media literacy above that of a 12 year old.
The humans and the bugs are ultimately not that different, especially by the end. Your defenses - the bugs are worse, the bugs started it - do not withstand a look at the text.
The teacher at the beginning (Rue McClanahan from Golden Girls lol) expresses admiration for the bugs - they're selfless, brave, don't know about death, collectivist. Denise Richards raises a reasonable objection, that humans have created art, and she laughs at the idea.
Even if the bugs sent the asteroid, the humans end up using Horten Ho 229s to bomb entire planets.
Neil Patrick Harris uses the same power as the brainbug - he's psychically guiding subordinates through the tunnels. The mobile infantry loses individuation and will power and exist only to die and kill, like the soldier bugs.
Then, at the end, the humans do the exact same thing the brain bug - they penetrate the brain of the brainbug with a symbolic phallus to learn how it fights to make its "race" easier to kill.
The movie is not "fascism is kind of cool when it's against genocidal bugs" because the government seen here is incompetent, ideologically deranged, helped start the war. The movie is "fascists, even if they come up against literal bugs, end up transforming dumb sexy Dawson's Creek kids into bugs."
Neil Patrick Harris is the only young actor in the cast smart enough to realize this. He goes from the smartass friend in a recognizable late-90s high school sex dramedy to "what if Reinhard Heydrich was psychic?"
