I don't know about that... if we allow the use of nukes to happen without stopping the one starting it, we just lost everything we have. Just later than sooner. It's not for the sake of Ukraine that I'm saying this.
It's for my very own interest that I want countries to bond together to eliminate a world-ending threat looming over my head. One way or another.
After all, the only reason why we can cripple Russia is because they won't use the nukes. If they'd be using them, that kind of reasoning is gone forever and that's why we as well have nothing to lose anymore.
After the first one is launched, it almost doesn't matter anymore if it's because someone beats you in a war or because someone used sanctions against your economy.
