You do not want Putin dead—unless you like the idea of a real fanatical Russian nationalist at the helm.
The successor may not give speeches announcing their attentions—they may just act—in a way no-one will want.
Spot on.
Be careful what you wish for—who ever replaced Putin could well be much worse. End the Ukraine war with a few nukes—all cities gone in a flash. Risky, but will Europe risk Paris or Berlin to strike back? Would Biden risk New York or Boston? (well, maybe Mira-a-Lago or Houston) Turn Ukraine into a poisonous zone of death. There are crazies all over. The war needs to stop! The killing needs to stop before we devolve into WW III and a total reset of the political framework of the world.
