What Trump also underestimated is that we don't just have a trade access problem with China today, we also have a trust shortage problem. When all we bought from China were toys and T-shirts and cheap electronics, we did not care if they were communists, capitalists, authoritarians or vegetarians. But now that China wants to sell us many of the same high-tech products that America and Europe make — from 5G infrastructure to cellphones to advanced electronics — products that get deeply embedded in our society and can be dual use (civilian and military), we need a whole new level of trust between our societies. That will take time to build.
