Actually, focusing on attacking china is a big mistake of this admin. It accelerates the decline of US hegemony as we know it. The best strategy for US is to maintain the current world order with China. Only the weaker countries "behind" US/China, e.g. India/Japan/Vietnam/Taiwan, would want the two countries to fight it out so they can benefit. And there are people in the US who believe a trade and technology war with china is easy to win, which are proven wrong.
