When D-Day came around, we needed all the help we could get. The US didn't win the war for us. The allied forces did. Canadians, Americans, Aussies and Britons alike. Russia pitched in too.
I don't think anyone believes or even hopes that the US will handle things for them. You have not shown yourself to be very capable in recent history. As far as it not being our problem - Iraq? Wasn't our problem, or yours. If we are going to overthrow brutal governments, why not start with Zimbabwe? At least a lot of the people there are of Anglo-Saxon heritage. But Zimbabwe does not have huge oil supplies, and that is why the US took no interest. You took no interest in the weapons of mass destruction either. They were pointed out to your leaders, and they brushed it aside. The war in Iraq did not start from the kindness of Bush's heart.
In short, I don't think there is an ounce of embarrassment in not thinking Iraq was our business. Dutch troups are in Afghanistan. Sadly they are also in Iraq. If I remember correctly, your president asked us to help.
Don't pretend you've won the war, or are winning this one, because as far as I can see, it's clear you can't do it on your own.
