It's the American way. And they are the 'leaders of the free world' and a supposed model for the rest of the world, or at least the 'West'. Through NATO etc. they wield a lot of power in Europe. However, with Trump saying stuff like he won't rule out using nukes in Europe, I'm not sure their inner conflicts won't spill out. US has a history of lashing out and not giving a damn about what happens to others as long as they project an 'air of invincibility'.
