You failed to complete the thought.
The moment "NATO" launches nukes at Russia to "obliterate" them, Russia will have their ICBM's launched and headed to the U.S., the U.K., France and Germany.
Not only would Russia be obliterated, the United States and Europe would be obliterated as well.
Russia isn't suicidal like the theocratic 7th century barbarians in the middle east. The tactical nukes would not be for use against Poland, they are for use inside Ukraine, for when there is an airbase with a wing or more of U.S. "donated" F16's stationed there.
Russia is putting nukes into Belarus to threaten NATO, not Ukraine.
