OK, Outsider. In fact you do show some improvement. More than half of Caterpillar sales are foreign sales. Trump's 45% tariff on Chinese goods would certainly meet retaliation. Of course there's some doubt about the actual scope of a trade war, especially when the best example is the Smoot-Hawley tariff Act of 1930, which did indeed start a retaliatory trade war, but to what extent it caused or exacerbated the Great Depression is still debated. Most economists seem to think there would be retaliation followed by world-wide recession. Isolationism and hatred of free trade, it seems to me, are mostly irrational reactions. Outsourcing of jobs has caused a lot of pain, but many of those jobs were eliminated by efficiency gains from computer aided design and manufacture, and other forms of mechanization. Free trade has brought us affordable consumer goods, important to low wage workers. In addition, the US is ahead of low-labor nations in process efficiency. Maybe we can compete.
