As I understand it, the real reason Saddam invaded Kuwait was because Iraq owed Kuwait an awful lot of money and wouldn’t pay it back. They then sold the debt to some international banks, giving Saddam a BIG problem and infuriating him so much that he just had to put them in their place.
Luckily it didn’t work, though I’m not too keen on Kuwaits lack of a democratic or free society either.
