America in Iraq: Evil or Incompetence?

"Have the chaos that followed the American invasion of Iraq, the subsequent breakdown of the country and the spread of senseless violence been largely due to totally unforeseen factors or were they due to incompetence?

If it was incompetence, was it incompetence at the planning / administration level or at the execution level?

Is such a level of incompetence possible?

Or… was it due to evil intentions at the planning level that created conditions leading to incompetence at the execution level?"

I would have to go with incompetence at the administrative level, I think there is ample evidence to back up that position. I do not see any evidence of evil or poor execution.
