@jmm99:

Tolerance is fine, but don't be surprised if very different attitudes lead to a separation. The USA could break NATO with its style - and would be pretty alone afterward. It's open for debate whether the British would stick to the USA in such a case.


@Entropy:

"They conflate the decision and rationale for the invasion with the poor execution afterward."

That's a key quote that shows that you don't use the European point of view.

It's not about whether the war is clean or dirty, successful or failure.
The Iraq invasion was pretty much a crime by European standards (and international law, but that's another story).
The act itself was not justified, not legal, an extremely poor tool for the purpose and overall it wasn't more reasonable than a random action.
