Economics is clear on nothing. The curve maximizing behaviors for international trade have a few assumptions built in, e.g. that Taiwan does not get annexed by China and suddenly the trade incentives change horribly.
I think the assumption is that when the system is threatened, the leaders of all the countries benefiting from said capitalism would grow a pair and do something.
Because if they don't, and the system collapses, then what?
The system has already collapsed if war is happening. The opportunity cost of economic trade is dependence. There’s more at play than basic competitive advantages to actual trade.
