Iraq was always fucked. They didn't invade Kuwait because they were bored. They invaded Kuwait because they desperately needed revenues to repay their war debts to the Gulf Arabs, who refused to forgive their debts and refused to cut their production levels, meaning Iraq's oil revenues were fucked while Kuwait, Qatar, and SA insisted on full debt repayment.
Sadden quite logically came after the Gulf, which is when SA called in its lackey, the US, to push him back out and protect their pyramid scheme against the northern Arabs.
It's always strange to me how people forget the devastating Iran-Iraq war, which in many ways is what determines the region's fate, as the Sunnis hurled Iraq against Iran in a hideous war and then ass raped their pawn state when it failed. Imagine being Saddam in that situation. It was like Germany post ww1, but worse.
