There is no more Free World and Biden is not their leader. George Soros has more power. Putin is playing a game of “Chicken”(Thats where two hot rods drive at each other to see who will swerve first. Don’t Blink!). I don’t think Biden’s up to this game of nuke chicken!
If Russia wants to play Russian roulette that’s their choice. The Pentagon tracks Putin 24/7/365 and if he fires a nuke at us ten will certainly be fired at him.
Mutually Assured Destruction never ended as a US national policy with regards to Russian NBC attacks on the USA.
They can shoot a nuke at us and we’ll shoot hundreds in response.
