Success in Iraq!

The Iraq War is over. Well, not really. There is still plenty of sectarian violence. But we have a stable democratic government. Not really. A government has not really been formed since the last election and the government is corrupt. At least we are bringing our troops home. Nope, 50,000 American troops remain in Iraq.
We've made Iraq more secure without Sadam. Not in my opinion. I'm still waiting for the majority Shia in Iraq to join forces with the majority Shia in Iran. And forgot the cost of the war in dollars (all borrowed), estimated to be 3 trillion. We were told the war would cost 50-60 billion dollars and Iraqi oil would pay for it. Thousands of Americans lost their lives, tens of thousands of Americans were wounded, and tens of thousands of Iraqis were killed(at least). For this kind of success?
