@ScottLucas They won't withdraw. They'll have to be driven out. And if that's the case then the sooner we get to it in earnest, the better. Ukraine is suffering terribly from an unjust invasion.
The Russians must be driven out with overwhelming force that does as much damage as possible. It's the only thing the Russians understand. If you play "nice" they laugh at you. Keep that in mind.
Also keep in mind that Russia is a paper tiger with an economy the same size as Spain's.
