So the thing is that it's not just the movie and novels that should be taken as separate canons, it's the first movie and everything else built off the movie that should be taken as separate, including the pre release materials.

The novel wasn't a satire of fascism (and wasn't fascist either, but that's a whole other thing).

The movie was, but Verhoeven fairly famously didn't read the book, and everyone around him knew what "due diligence" means so they did the bare minimum, so all the other material built off it has a different direction.

That said, Buenos Aires was definitely a false flag/accident in the movie.

I don't know if you know much about space, but a small amount of energy applied to an object at a distant point can have significant implications for the trajectory of, say, an asteroid traveling through space.

We see the asteroid that hits Buenos Aires, and a Federation ship bumps into it in space.

It couldn't possibly have been on a ballistic path to take out Buenos Aires, that bump would have made it miss.

But, okay, maybe it was just lobbed in Earth's general direction, and that was just a tragic accident? (This is what the supplementary material goes with btw)

With what technology?

The bugs in the movie show absolutely zero technological use. Not one bit.

These are the questions Verhoeven wanted you asking. They're also the ones every other bit of material ignores, despite the clear criticism (if not actually fair to source) laid out by the movie.
