Why would the US or the west or China wants to start a war? Over what? They don't have any disputes about land or people. Just some irritations about whatever.

Why would the US or the west or China wants to start a war? Over what? They don't have any disputes about land or people. Just some irritations about whatever. But certainly not recipe for war.
