Doesn't make faking (albeit badly) this 'essay' right though, does it?
I don't trust ANY politician, full stop. Whilst it would be nice if stronger countries acted with more insight, and higher morality, the sad fact is that a country's leadership is primarily intended to ensure the best deal for their own citiziens, morality often has to be sacrificed quite early on and I doubt very much that any country throughout history has ever acted for a moral reason without there being some benefit to be gained along the way.
As for the US, they've not been overly delicate in Iraq but then having conqured the place they are attempting to leave it rather faster than most conquerors would walk out on such a resource rich part of the planet. Leaving behind a US disposed government is not unexpected, but provided the Iraqi people have the opportunity to self govern, and replace this ruling council by democratic means, then I'd have to say that - on balance - the US is performing reasonably creditably compared to most winners in history.
