As the Americans intervened to liberate Kuwait, the UN and the US imposed heavy sanctions on Iraq. This caused the Americans, and especially particular fractions within the republican party to want to cause a regime change In Iraq by getting rid of Saddam Hussein. After 9/11, which was perpetrated by radical Muslims with the support of former Mujahedeen who were previously fighting the Soviets in Afghanistan with the support of America, the United States set on a path to reshape the Middle East region to better answer to its interests. That is one of the main reasons why the US invaded Iraq, an operation that failed miserably and caused the Sunni resistance forces in Iraq to organize themselves. This, in turn, attracted many extremist Muslims willing to fight Americans and Shia Muslims in Iraq. This eventually led to the creation of ISIS, which further grew after Syrian rebels started to fight the repressive Syrian government.
