1. US Invasion of Iraq 2003The 2003 invasion of Iraq lasted from 19 March 2003 to 1 May 2003 and signaled the start of the conflict that later came to be known as the Iraq War,
Iraq War was a terrible mistake and violation of U.N. charter. The war aimed to make Iraq a model of democracy based on law, but it replaced tyranny with anarchy and led America to practices that violated the laws of war.
The war aimed to transform Iraq to a friendly base for U.S. troops capable to act, if needed, against Iran—but instead it gave Iran a new ally in Baghdad.
The US army had to finally withdraw leaving the country in the throes of a civil war.
