This is a re-post of an essay I wrote earlier this month for The National Interest. Basically, I have been amazed in the media discussion of the Sino-US trade war at how little effort there’s been to explain why it might be a good idea – namely, if you accept that China is a serious medium- and long-term threat to the United States.

Now you don’t have to agree that China will, in fact, become  that threat. Scholars like Dave Kang don’t think so. If not, then the trade war is just a foolish distortion of the comparative advantage benefits both sides reap from trade. It is then strictly an economics question, where Trump is indulging foolish protectionist instincts which woefully misunderstand that a US trade deficit is not a a problem to worry about.

But if you do think China is a looming competitor, if not a serious threat, then the logic of scaling back China trade is pretty obvious – the political benefits of slowing China’s rise outweigh the economic benefits of its cheap imports and T-bill purchases.

This line of argument would actually be pretty persuasive to a lot of people. I think there is a growing consensus in the natsec community that China is a real threat. Hence Trump could find new allies for his controversial trade war policies. But he never makes this pitch – I presume because he is too obtuse to actually understand this argument. Just in his Wisconsin speech again yesterday, he instead made the same ridiculous argument that the US trade deficit with China is China ‘ripping us off.’ Whatever…
