Putin sees no need for nuclear weapons to win in Ukraine. But he's also keeping his options open

The message to NATO from President Vladimir Putin was simple and stark: Don't go too far in providing military support for Ukraine, or you'll risk a conflict with Russia that could quickly turn nuclear.

As the war in Ukraine turns slowly in Moscow's favor, Putin declared he doesn't need nuclear weapons to achieve his goals. But he also says it's wrong for the West to assume that Russia will never use them.
