IF! The world formed a solid block. Now that right there is something to worry about.
Let them form their solid block. There is nothing to worry about. The USA is the money basket of the world. They will be blocking themselves out of the money basket for as long as is necessary. Eventually they will learn which side their bread is buttered on. Meanwhile, I will be happy to see more US motor vehicles on the roads and in the parking lots of America. BMW’s and Mercedes annoy me, to say nothing of Toyota. Americans just might learn to buy American again and find out that all the garbage promoted by AntiAmerican auto manufacturers just “Ain’t” True. “Prestige” vehicles don’t get you there any faster.
