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.
