That's not the point. Everyone is talking about the little economic/trade/tech/diplomatic/people gains that Russia would have from attacking Ukraine while neglecting the fact that NATO is building Ukraine to be what Taiwan is to ChinaEveryone in the Donbass who wanted a Russian passport was able to get one. It would be cheaper to relocate those people inside Russia than take on the dead weight that is the Ukrainian economy.
Unless Biden gives solid guarantees to Putin, Russia will attack Ukraine for geopolitical and military reasons. It is impossible for Russia to tolerate NATO arming and training the Ukrainian military
