Depends on what one gets in exchange, I suppose.
Would that be such a bad thing if all nuclear weapons were dismantled and threats of mutual destruction taken off the table? There's probably any number of trades that could be made.
Would have to hear the term sheet. Just because for the Cold War period we were indoctrinated to hate Chinese and Russians doesn't mean things haven't changed. We hated the crap out of the British too in 1776. We hated the crap out of the Japanese in 1945.
Things change.
Things change but the reality is that the entire free world (outside of Trump and MAGA) views Russia and China as threats to freedom. Russia is currently trying to subjugate a sovereign state and China is illegally taking over the South China Sea and encroaching on the territorial waters of other countries.
The only thing that is changing is that we are acting like them now. That is not a good thing.
