Snakey, I'm sure you believe this strongly.
Actually, that's a large part of your problem.
What does Cuba owe you? Or Grenada? How about Venezuela?
I won't go into the Iraq thing, at all....
I'm also sure you believe Australia owes you too, but from my POV if we did owe you anything for WW2 (and I think it would be considerably less then you would guess), we have more than made up by assisting in your country's more recent mercenary endeavours.
Bottom line, the balance sheet is probably pretty even between helping and hindering, not enough to be too proud about.
