This is not about a “moral high ground” or some deep commitment to utilitarianism (which you somehow turned into a bizarre rant about electing Hitler).
I am talking about a practical, real life evaluation. Of course many people vote based on emotional reasons, but that doesn’t mean tactical voting is not extremely common (perhaps even a majority of voters).
And the fact remains that even people who have a strong emotional motivation can still be willing to make tactical choices. It’s not all black and white like you describe.
Ukraine is the only country in the world that has the full moral authority to develop nuclear weapons. We are the only country to give up nukes and look where that got us.
That being said “moral authority” isn’t worth shit in this world.
South Korea, Poland and the Baltic nations should honestly try and develop their own nukes too.
