Yes, he described Palestinians as “the bugs” and said some other really fucking ignorant quotes from that movie without the slightest understanding of Paul Verhoeven’s intent (his effort may have been doomed from the start; he even scolded actors on set for “not getting it” and just enjoying the fascism).
I have some license with what I say because I’m moving and transferring out of state in a few weeks but I also don’t want to have a bad mark on my record by saying something particularly scary about the IDF, so what should I tell him on Monday?
Tell him that the Buenos Aires attack was obviously a false flag operation by the humans to declare war on the bugs. Show him this map and ask him how a bunch of bugs who don’t even have basic vehicles let along spaceships was able to propel a giant rock halfway across the galaxy to precisely fit a major city and not just miss the solar system altogether. Not-so-subtly insinuate that only the most clueless rubes would fall for this in-universe bullshit and that said clueless rubes who totally bought an in-universe narrative that’s even implausible by WH40k standards are even more clueless about the complexity that is real life which does not benefit from a film director hitting said clueless rubes repeatedly over the head with the themes of the movie. Do all this in the most smug voice imaginable.
It might backfire if he’s one of those irredeemable Roman fappers that thinks “casus belli” is based and not a horrifying doctrine, you know, where his side and whatever it does to get ahead is “based.” He does seem to be the “Manifest Destiny was cool and good and so was the slave trade because they both elevated primitives out of mud huts” type, especially after I argued once about the blood price of lithium and he countered with something about “mud huts” and “wasted resources” untapped beneath those mud huts that could be used instead “for the mission”

Holy shit
Problem: The movie addresses the asteroid in a previous scene (hits Carmen’s battleship, disables communication) and this chud will pick up on that immediately. While I like your idea generally, in this specific case this dudebro will have an obvious counter.
That’s why I mentioned WH40k. There’s no sci-fantasy setting save for WH40k where a starfaring civilization could even destroy a city that’s halfway across the galaxy without using what present civilizations of that setting considers ancient for-all-intents-and-purposes-magic (eg Forerunners, Xel’Naga, Protheans, Celestials). It doesn’t matter if it’s Star Wars, Star Trek, Starcraft, Halo, Mass Effect, Dune, and so on. WH40k could get away with it through warp shenanigans as in the civilization shoots the rock through a warp rift and have the rock appear on the another side of the galaxy to strike the city.
That might work for convincing him that the humans in starship troopers are wrong but it would probably be more relevant to the point actually intended to point out the various ways Israel continually brutalises and marginalises Palestinians
