Not any kind of expert here. What COULD be provided that might force the Russians to withdraw and settle this to stop the dying
On both sides? Anything?
What could be provided? Ukrainian nazism being ended and NATO shutting down the Ukraine project.
I suspect you were wanting to hear what weapon might do the trick. But there is no such weapon. Any weapon provided that “improves” things simply moves everyone a step up the escalation ladder. And at the very top of that ladder is the largest nuclear arsenal on earth on the Russian side.
So your escalation plan is that if you inflict a military defeat on them with some wonder weapon, they will slink home in humiliation, pay Ukraine a bunch of money, and install a government the DC/London axis approves of.
In reality, if with some wonder weapon, you could drive them back, they will go nuclear in the face of that existential threat.
Bottom line, you are gambling that a nuclear armed nation would prefer complete defeat over using their most powerful weapon. Would we in America accept complete defeat of our military, rather than use our weapons?
Herman Kahn says probably not.
