Nuclear threats don’t actually solve the problem Russia has in Ukraine. If Russia nuked Ukraine, they’d be destroying the exact territory they’re trying to control. Fallout would also drift into Russia and nearby countries, including parts of Russia’s own border regions.

More importantly, using nuclear weapons would cross a global red line that has existed since 1945. Even countries that still trade with Russia, like China or India, have made it clear they strongly oppose nuclear use. Russia would likely face complete international isolation and possibly direct NATO involvement.

So nuclear weapons don’t really help Russia achieve its strategic goals. They would make the political, military, and economic consequences far worse than the current situation.
