Entirely different cases. Russia never relied on the strong rouble for its economy to function. Or having unfettered access to most of the world's markets. So it had some know-how on weathering the storm.

But OTOH, if Trump is erratic enough to trigger a world-wide de-dollarization trend, and close down markets that were traditionaly open (e.g. Europe), then US would be facing an unprecedented storm that would be much harder to navigate.

Have we seen any signs of any limits to erratic behaviour?
