Going to call nonsense on the headline: NATO is intact, and Putin wouldn’t dare invade a nato country.
Trump it’s the caveat, but even in that event France and the UK have a nuclear umbrella, and there is a shit load of troops. A war with NATO is unwinnable for Russia for certain.
Ukraine danced with the neutrality devil and lost, just as Belgium on WW1 did, and the NL of WW2. Any country now adjacent to Russia and not in NATO has a choice: risk the neutrality game or side with NATO. I know which I’d be picking.
