What is this referring to?

This made me chuckle a little bit. It was definitely directed at the bush government, but I do not recollect any invasions of Iran... [[Iraq did this?" No peter Iraq had nothing to do with it.. It was a group of Lebanese, Egyptians, and Saudi Arabians, being financed by a Saudi Arabian guy living in Afghanistan , and sheltered by Pakistanis.. so........... you're saying we need to invade Iran?]] It's from family guy, about 9/11.
