So if Russia gets a big chunk (or all) of Ukraine they will not only have one of the largest reserve of oil in the world but also control of one of the largest food exporters in the world. I don't think the West wants that. And Europe wants that buffer zone. The U.S. won the Cold War by outspending the USSR. They can do the same now. At the same time, everywhere the U.S. retreats from, whether its military aid, humanitarian aid, trade deals,... China will step in to fill the void. Trump on Mt. Rushmore? More like Mt. Flushmore".
