Resolved Question Why did the rest of the world let the USA military invade Iraq.? As I understand George Bush committed a war crime by invading Iraq. He said that they had WMD's but they didn't. He said the were responsible for 911 but they (Iraq) weren't. So can someone tell me why the UN executed Saddam Husein for crimes against humanity but George Bush doesn't even have to explain his actions to the UN. Best Answer - Chosen by Voters The world isn't stupid enough to declare war on us and we have NATO on our side. The US and it's allies invaded Iraq because Saddam violated 19 resolutions as well as the ceasefire agreement placed after the 1st Gulf War. Plus George Bush and Tony Blair(UK) did not commit a war crime in a war that has been going on for decade during the Gulf War Ceasefire Agreement. FYI, Saddam was executed by his own people, not UN and NATO. The Iraq War was NOT a new war and started by US as many Anti-Americans claim to be. Saying the Iraq War was a new war shows lack of knowledge on that situation. The 1st Gulf War was started by Saddam when he invaded Kuwait in August 2, 1990 in order to steal their oil fields. After 2 days of fighting, The Kuwait's army was defeated and Iraq manage to occupy Kuwait. The 1st Bush administration decided to ask the UN for help. After Iraq invasion of Kuwait
