Here is a link to my latest column at the Library of Economics and Liberty. A slice:
One last point on the national defense argument. If China, a national security threat and military threat for influence in the region according to President Trump’s economic advisor Peter Navarro were dumping steel in the U.S. market to gain some military advantage, the logical thing for the U.S. government to do would be not to encourage U.S. exports but, rather, to encourage Chinese imports. Since steel is a scarce resource, sending it abroad (i.e., encouraging exports) necessarily reduces the stock of steel in the United States, whereas imports increase it. If China is dumping, then it means that the product is being sent to the United States rather than being used in Chinese markets; for every unit of steel sent to the United States, that is one less unit that could be used for a Chinese war machine and one more for a U.S. war machine. The logical action for the U.S. government would be to purchase a lot of low-cost steel from China and simply stockpile it, thus depriving China of war materials while maximizing U.S. steel stockpiles. In the event of war, the United States would have a large stockpile from which to draw, while China’s would be reduced.
