Here is how. Impose total blockade of Russian oil exports/ Baltic Sea/ Black Sea Cripple China with 200% tariffs if they in any way aid Russia Ditto to India Give Ukraine Missiles to hit N. Korean weapons shipments in FE Russia/ This will lead to economic depression in Russia/ which will lead to Putin Regimes Fall. Thus Russian troops will have to leave Ukraine to put down internal revolts. Thus Trump will be second Reagan.
I think Obama is a better parallel. In your scenario, Trump would continue Obama's tradition of winning a peace prize through massive human suffering.
President Trump should have already won the Nobel Peace Prize if for nothing other than the Abraham Accords. But, we all know how political the Nobel Committee became and fawned over Obama for absolutely no reason. The Committee could redeem itself and award the Nobel to President Trump who, rightfully, deserves it.
