Cut the Russians off the the international banking system and watch the Russian economy crash and burn within 30 days. Putin will come to heel or his gangster friends will kill him.
They will just buddy up closer to China either over or under the table.
The only way this will work is if we also put sanctions on Russia’s allies, including China, Belarus, and Kazakhstan (if they dont play ball); and start a massive arms buildup in Poland and the Baltic states. We also may consider a ground invasion of Cuba and assassinating/arresting the leader of Venezuela.
