After 9/11 Americans were extremely angry, but at the same time nobody knew just who did it. Some people placed the blame on Saudi Arabia and Pakistan, and on September 13th, 2001 the embassies of Saudi Arabia and Pakistan in Washington DC were broken into. While nobody was killed (though some embassy workers were assaulted), the US government apologized and those responsible were sentenced to twenty years it caused a lot of ill will in both Saudi Arabia and Pakistan towards the US.
Had this not happened, how differently would the War on Terror gone?
