Predictable
The effect of politicians clumsily inserting themselves into global supply chains isn't quite what they anticipated. They have rather simplistic notion of control -- they can beat down the opposition by starving them of essential parts, bending them to our will etc. etc. (whatever that actually means), a view that may well work when the country is tiny compared to them. Once they start screwing around with countries that are many times their size then the other lot are going to react, and they'll react by filling the gaps. (This may take a few years, its a process, not a singular event.) Suddenly you've got all the production that we used to sell to this market surplus and to compound the problem that once large market is now making parts for sale to everyone else.
Personally, I put is down to a surplus of lawyers and accountants in US decision making. They haven't a clue how things work, they're just used to issuing orders and things happening ("or else"). Too bad real life doesn't always obey the paperwork.
