I may sound antiamerican, but I'm not. I'm anti-bush, not antiamerican, in fact I'm grateful for the postwar help they provided and for helping kicking out the nazis .
It's true that in the Malvinas war (Falklands) US didn't allow to use US soil, but they never had to, as Chile helped England in all what they needed. From US' view, what they did fear IMHO is a communist South America at those times, and Argentina hadn't such a government. That's why they sat on the fence, but not that UK needed their help either... you lot have the second best army of the world AFAICT (at least in techonology, maybe the Chinese is greater in numbers, but still).
