No fly zone?

 I disagree with these politicians opposed to a no fly zone over Ukraine. They believe enforcing a no fly zone will get us into WW III. It's just the opposite. The weak stance doesn't work with Putin. He didn't invade to fail. He seems to be in it to win. Nukes are still a huge potential. When the first missile hits here or there, we will have certainty of that. Hopefully, I am wrong, but I doubt it.
