That wasn't really 'aggressive' was it? SH invaded Kuwait and wouldn't leave. I suppose they could have just left him there, but like once they kicked him out they fucked off again.
Depends which narrative you subscribe to, but I can overlook this one since I was too young at the time to understand what was happening. I might be wrong to assume it was avoidable with a better policy.

Nowhere near on the same scale as IWII though.
Is this a typo? You mean GWII? Syria is utterly destroyed, it's a terrible situation. Obama also has drone attacks in Pakistan that have killed many civilians. He's not getting a clean pass.
