If someone did something like that we could get worse. Think WW2. Hitler was an absolute hero to a demoralized people. The Russians have been demoralized for a while. This invasion gives them the taste of power they have longed for. Do something to the guy giving them the power and they will put a worse tyrant in his place. Not sure what the solution is, but I sure wish we were in military shape to handle the challenge right now. If Bambi gets elected, we will pass the point of no return in that regard.
Unfortunately Putin is not the only problem. The Russian liberals should have pushed to have all the Commies and KGB types put on trial, liquidated, or at least rooted out of office everywhere. That should definitely be done by all the non-Russian nations of the former Soviet empire. Instead, they have allowed ex-Commies to reorganize and run for and win control of their govts. at times. The only good Commie is a dead Commie.
