History does not show that tariffs will restore economic activity. You are looking for scapegoats and easy solutions. Tariffs will exacerbate problems of non competitiveness, increase prices, and make US industry non competitive. In addition, the hair-brained scheme that you suggest will cause a global trade war leading to reduced economic activity across nations. The world is very interconnected in commercial dealings. You are proposing to return to a bygone, idyllic world dominated by high tariffs. This bygone world does not exist anymore.
In time of real war, like a WWII scenario, who makes the ships, planes and tanks for our armed forces?
