It's not trade, it's US facilitated trade via the Bretton Woods system which has enabled free trade between countries that previously went to war over resources (among other things). Much of global trade is facilitated and protected by US empire.

I'm not being jingoistic, and am very cynical about US intentions, practices and policies, but the reality is that without US military hegemony, countries that fought for resources, like on the NEP, might again.
