I saw on the news last night that several currencies have gained substantially in value against the US dollar, all for the same reason: the American economy is in very bad shape.

This president is not taking care of business at home, which makes him a bad president. Aren't leaders elected to manage their own countries primarily? So while Bush is grandstanding, making war, being theatrical and carefully timing his speeches for sound bites, the American infrastructure, schools, health care situation, inner cities, etc. are all deteriorating further.

Although I can't predict how the US might lose its power, I think it will be from within, and that the current situation will powerfully contribute to the downfall.
