It won’t start a nuclear war. Ukraine doesn’t have nukes, they’re not nato, and we’re not gonna get Washington nuked to save Odessa.
You said nukes, you think that Russia can start launching nuclear missiles in Europe without it spreading, where does all that fallout go, how do defense systems know that the missiles being launched are going to THAT city and not THIS city?
NATO is tolerant but they are going to ignore a nuclear attack being launched on their borders and poisoning and killing their people and nations?
