Putin started threatening nuclear war on the first day of his invasion, on the third day he put his nuclear forces on alert.
Putin has been hammering the nuclear threat ever since, constantly, and having his agents and state media constantly threatening nuclear weapons and war.
Putin has been trying to normalize nuclear weapons for use in invading a neighboring country, normalizing them to stop anyone from aiding the country under invasion. Putin is trying to sell nuclear weapons as usable for normal warfare.
The United States of America, the Western world, and the rest of the world cannot allow this to happen and cannot surrender its foreign policy in advance to every nation with nukes.
Oh, just take a look at how this conversation was handled by EVERYONE in the world for sixty years until the media masters changed the narrative to the world class idiocy you’re talking. Good Lord! You’re going eyeball to eyeball in this nuclear pissing contest over, “well SOB, the prosecutor got fired”! Do you really think Biden is risking my nine grandchildren over Ukrainian freedom?!? Even if he was, what concern is it of America? The only time Russia ever attacked us was in Hillary’s paranoias. Insanity.
