I think the US needs to focus on national debt, budget deficits, internal issues /and/ foreign policy. Discussing foreign policy as an isolated case is not really relevant in my opinion.
I would agree with your thoughts Rolf, as would most of the citizenry here in USA. But I would counter that actually making progress in any of those areas is much more difficult than you would imagine.
I read an article (posted earlier) about debt:GDP ratios by country and it would appear in my view that most developed countries carry ratios of 75% or higher (debt to economic ability), which ironically appears to be about the same debt:equity that banks require for personal loans.
I think the government being debt free might inadvertantly cripple the financial services sector of the global economy?
