Yes, I share the same concerns. Frankly I’m not sure what can be done on long term security when Russia has demonstrated its willingness to threaten nuclear weapons. I wonder if Putin being no more would result in a different Russia, one which isn’t focused on expansionism.

I don’t think this is the intention of the U.S. negotiating a peace deal, but a pause could give time to let Ukraine and europe to build up arms. I might be wrongly optimistic but I suspect a build of arms across europe would result in a more powerful force than Russia alone.
