Replying to Help me with my international relations homework

this is a bad fucking idea posting on here but im really braindead and need some help.

So i have to write a paper on an International Relations "puzzle." Basically, answer an interesting question on why a country acted in a certain way towards another country, and compare it with another event. The example was "why did the US invade Iraq in 2003 and depose Saddam Hussein, but didn't invade when it had the chance in 1991?"

If anyone has any interesting questions about world history post em up here that would be awesome

to everyone who is going to troll in this thread, heres a preemptive message - fuck you - but maybe i'll get some good ideas from a troll post so i aint even mad
