Why do you think nuking Russia would be unacceptable in the hypothetical situation of Russia instigating by launching a nuclear attack against Ukraine first? Why do you think that only we are responsible for being mindful of mutually assured destruction in the event that Russia is the first to use a nuclear strike in this war?
Why do you think Putin gives a shit about Belarus? Why do you think Putin gives a shit about Wagner, a group that recently planned to march on Moscow to engage in a coup? What am I missing here?
Do you understand that a nuclear strike on Ukraine means nuclear fallout kicked up into the atmosphere? And that wind will definitely carry that fallout into NATO airspace? And that this would be recognized as an attack upon NATO which would trigger article 5?
Russia is making incredibly stupid decisions, but I don’t think even they are dumb enough to launch a nuke at Ukraine. At a time when they already appear to be villainous weaklings, this would just invite direct action to ensure complete destruction of Russia. So far in this campaign, they’ve only seen the results of a few allies donating weapons, ammunition, and training to Ukraine to use in defense; imagine all branches of militaries of the west directly involved in an offensive with the goal of showing the world what happens when you nuke our ally without cause.
If they launch a nuke in this war, it should be viewed for what it is: the frustrated whimpering of a dying nation, desperately gasping for breath while its lungs fill with blood.
