The US government doesn't realize the implications of their actions. A day will come when the US needs German help, support, or assistance in an area of global importance and the Germans will be very reluctant to help because of this Presumably you're referring to the US invasion of Iraq. But I don't think something like the German refusal to cooperate back then is going to happen again. All that matters is money, and German's economy is (solely) based on exports. They need the American consumers for their own good, and German cooperations will make sure they keep their markets.
