I agree with the sentiment that isolationism is not the answer, but I also think we need to accept reality that as the US falls apart our global supply chains are going to be incredibly vulnerable going forward. I don’t want to end foreign trade, but the extreme fragility of just-in-time supply chains is simply not going to be an option, likely ever again. If we cannot provide at least a minimum level of self-sufficiency, we cannot consider ourselves a legitimate nation. Period. If the US decided to enforce an illegal embargo on Canada the way it’s doing to Cuba right now, how long do you think we’d last? With the human and natural resources we have, there is absolutely no excuse for the fact that the correct answer is “Not very long.” When you live next door to a nation of pirates, raiders, and thieves, not being capable of weathering a siege is incompetence and mismanagement. Having a minimum level of strategic domestic production of everything from glass, to chips, to refined oil products is table stakes.
