Where to begin. It's not a double standard because the situation is entirely different from 1945. Do you really not understand this?What are you talking about? Ukraine doesn't have nukes either. I thought it was an interesting point.
Here you have the US bombing Japan to save lives over all (which I think it did)
But if Russia were to use them in Ukraine to save lives theres a problem?
Thats a hell of a double standard dont ya think?
If Putin's goal is to take and control Ukrainian territory it doesn't make much sense to make part of it a radioactive wasteland. Plus it guarantees an ongoing insurgency.
Finally, as spat has patiently explained to you multiple times, there will be no such thing as a limited nuclear war. Once the first nuke flies, they will all start flying. Clearly you live in some fantasy world where Putin can use a nuke in this day and age and the rest of the world shrugs.
So no, it wasn't an interesting point it was a ridiculous and unserious one. Why you thought it had merit is beyond me.
