He hasn't thought through how many Americans will lose their jobs; how many countries will retaliate; how long it will take to be able to manufacture everything needed for a society to succeed/survive; and how small a market U.S. manufacturers will have since no other country will buy what we make and only a third of us will be working and be able to buy anything. And since unemployment numbers will be stratospheric the Treasury will be broke from paying welfare and Medicaid benefits.
