What "provokes" Russians like Putin is only one thing, and that is our weakness! Nothing else matters.
We demonstrated laughable weakness in our skedaddle from Afghanistan, and Putin drew the obvious conclusions -- that we'd do nothing serious to stop him in Ukraine.
Today China's Xi is watching carefully to learn what not to do when he invades Taiwan.
Maybe we will learn a lesson or two also?
I'm more concerned with China and their grabs in the S. China Sea & in the greater Pacific Ocean. If our so-called leaders were looking after our well-being, thy'd be dealing with that instead of throwing away our resources in Eastern Europe.
