Yeah but the interests of the rich would tank more than those of us other 99%. Here in the USA, a trade war with China would benefit low income people and cause a Stock Market collapse.Aye, that could be a really really big conflict.
And boy, would their economy tank more than ours!
Trump could keep a lot of his campaign promises by slamming China with sanctions. Trade sanctions, financial sanctions, Trump could give the Chinese good reasons to deal with North Korea. But I don't think he will because he doesn't care about America. His interests are more aligned with Russian interests, and Putin doesn't care about North Korea much.
