“WE” as in the US no.. “WE” as in NATO which would include US troops yes. We need as they have said they are going to do reinforce Eastern Europe with mobilized NATO troops. You just don't let Russia do what they want to who they want. You let them know it's going to be not only economically painful but militarily painful that if they continue their aggression their will be hell to pay. We don't have to stoke the fires, just put the necessary people in place to make sure we will sure as hell put it out.
You might do that. I might do that.
0bama won’t do that. Merkel won’t, France, UK, etc. won’t.
So, Putin wins, without a downside so far as he can see.
That’s dangerous. Putin is just a garden variety bully who will take and take and take until someone bloodies his nose.
Who will ever pop him in the nose? I see no leader on the horizon willing to stand up to him. So everyone loses to the kleptocrat bully for the foreseeable future.
