SF satire is a fairly niche genre
Orwell's '1984'?
1984 is a brilliant vison of dystopia, but I would not classify it as SF or satire. It is surely closer to Brave New World by Aldous Huxley than Starship Troopers.
Ah, I do love the attitude exemplified by my mate Jim:
SF isn't literature. So if it's literature, it can't be SF.
Both the Huxley and the Orwell are SF.
"Iain Banks' first novel.....as 'Iain M Banks', he has also written a number of Science Fiction books"
As for Starship T, the book is excellent and Verhoeven didn't read it. Heinlein's deconstruction of the phrase "juvenile delinquent" is a classic, as well as his reply to "violence never settles anything".
The twist in the book, totally ignored by Verhoeven, is that the All-American-Blue-Eyed-Boy Johnny Rico is actually a Filipino.
