And the difficulty in spending this much comes in two ways:
a) The more important your hammer becomes, the more everything looks like a nail. The US has frequently undertaken a military response for areas where other countries might use diplomacy.
b) The military, plus contractors, plus jobs that depend on the military, plus PR and lobbying firms, all tend to distort politics in favour of increasing military importance.
Don't get me wrong: the UK and EU in general owes a lot to US military power over the years and should thank the US for a lot of our freedoms. But there is a flip side, and I think it should be recognised that such a large amount of spending does distort things.
