text: We invaded Iraq because Bush thought that Saddam was hiding the WMDs from the inspectors even though the UN and the Dolfer report (US sent own people) said that they didn't find any. Bush didn't believe the reports and went in. Simple as that.\nI see that a lot of people talk about pre-Iraq invasion and oil. I'll answer some of that. First, Saddam's rule was a dictatorship that oversaw massive killings, rape, torture, kidnaps, etc. (Did you know more Iraqis died under Saddam's reign than in the Iraq War?). Given that, I'm extremely happy that he's not in power anymore. And the reason I just mentioned was one reason for entering Iraq (which I believe). The current situation is that Iraq is a mess, and since we blew up their country, we need to stay to fix it (we broke their leg, we need to be their crutch until they heal). \nThe liberation of Iraq, to me, is a good reason for entering. Now the next thing you'll hear about is oil. Oil is not the reason why we entered because there is absolutely NO PROOF that we did. So that's out of the picture. In the beginning of the war, the American public was told that Iraq had WMDs (none found), Saddam would attack us (highly unlikely), and that Al-Qaeda and Hussein had connections (false). Those were the 3 main reasons that are PROVEN. The 4th reason, the liberation of Iraq, was given later in the war.\nAccording to the Washington Post (20 minutes ago), 500 weapons(nerve agents, sarin gas) were found in Iraq since 2003. The document containing this information was just declassified.
