Greenbacks' trouble?

Our former prime minister Dr. Mahathir warns that the United States have an US$7 trillion loan and that means trouble for the greenbacks. I wonder if its an outstanding loan or something. Could the American's government repay the loans in one go? I don't think so. That's why we don't really do it that way, right? He even have to say 'unless of course they (the US) change their President and have a more responsible President who tries to reduce the deficit'. *roll eyes* What do you mean by that? You know, George Bush cannot run for presidency anymore. After his current 4 years tenure, his out mate. That's the law. So are you saying some economical catastrophe would come within this 4 years? Sounds like FUD to me. I wonder why our former prime minister is spreading FUD. Sounds a bit fishy? No? With no other data but that US$7 trillion loan, its bad to based your judgment on just that figure. It could mean the other way right? You know, the one that says the US economy is healthy enough to accept that kind of loan? *sigh* But then he said, the greenbacks is not collapsing because of FUD? Isn't that more FUD? And he said because some people still used it? And why are they using it again? Devalued 50% against the Yen. Did the Yen went up dramatically or did the US went down, in what period of time? Within how many years? Is it because of the war? How much deficit again? Why is it doubtful that the greenbacks is not recovering? Didn't Malaysia trade a lot of with the US? Answer? No? Yes? Maybe its just the way this damn newspaper reports it. God, its misleading and I have too much questions then answers. Did I miss something though?
