First of all, since when has the US NOT put its own interests first? Never. Secondly, 95% of the world is not American, we've got most of the clout. If the US starts a trade war, we've got plenty of ammunition to fight back with. Of course a trade war is stupid but the responsibility for that rests with Trump. Thirdly, Trump has a lot of opposition...from his OWN party, especially on trade. Fourthly, China will soon have a bigger economy than the US, expect shifting alliances. The world also needs to grow up and stop depending so much on the US. This will be good for the world.
