How about we just stop invading other countries where we know people don't like to see Americans? If we had opted out of the second Iraq war, we could have saved thousands of lives, billions of dollars, and our own collective faces on the international stage. To top it all off we wouldn't need to be having this discussion at all. We didn't accomplish anything with that war.
I know that is not a popular opinion here, but it is the truth.
Under the sanctions, Iraqis were suffering. The child death rate was soaring, there were food shortages and there were thousands of deaths. The power of Saddam Hussein was actually growing and he was getting richer and more powerful while the population was suffering.
Which was all caused by the first Iraq war which was the result of arming Saddam Hussein so that he would fight Iran. We were fighting Iran because they were hostile to us because of supporting the unpopular Shah dictator. We supported a military coup that put the Shah in power because oil was nationalized by then Iranian government. The Iranian government nationalized the oil fields because they were outright owned by foreign oil companies and didn't think it was fair. I don't know what happened before that.
Just a chain of dick moves and greed all the way.
Other nearby countries using their oil resources wisely have done very well and are the countries with the highest per capita.
