When the US invaded Iraq (right or wrong is a moot point) then when we withdrew we left a power vacuum, an unstable government and degraded police/military force which was incapable of maintaining the security of the citizens. You will also have to agree that the same thing took place in Libya and probably will in Afghanistan. The only time in recent history that the US "did the right thing" is in the post-war occupation of Japan and Germany; yes the ethnic makeup was different than what we find in Iraq, Libya, and Afghanistan.. Everyone, well almost everyone, admits that what has happened in Iraq was basically the fault of the follow-on government and the rift between the 3 major entities of Iraq; the Sunnis, Shies, and Kurds. It is my opinion, that it was the fault of the US politicians that allowed this to happen. They made the assumption that since a "democratic" government was in place that everything would be just hunky-dory. Yes, it would have taken a heavy handed policy to ensure that what happened didn't happen. I don't know how long it would have taken to ensure that to happen, but I look at it this way. We broke it and we now are responsible for the country. I am going to go out on a limb here and say that a majority of the countries in the Middle East and Africa would have been better off, security wise, if the meddlesome Western powers would have left them alone and went with the policy of....as long as you are not directly or indirectly threatening us or our allies we will leave you alone; however if you do you can expect swift and harsh retributions (without taking out the government).
