If Russia uses tactical nukes then god help us all. If one though we were living in interesting times at the moment, they will soon think these are boring times.

If a country invades a neighbor, claims it’s now part of their sovereign homeland while the neighbor is still actively defending, and then uses nukes based the justification their newly occupied “homeland” they just invaded is being invaded by its defenders then it means any country with nukes can use nukes to invade and grab neighboring territory

At the very least, everyone is going to get nukes
