Ukraine would have a free hand to hit Russia’s territory, with whatever weapons it could obtain.
Doesn’t Russia have defensive pacts of their own, with North Korea and CSTO: https://en.wikipedia.org/wiki/Collective_Security_Treaty_Organization#History
They would undoubtedly claim to be attacked if Ukraine uses weapons in “their” territory the next time around, and at the very least drag Belarus (and NK as an explicit supplier) in with them.
Very interesting, but I wish the analyst had “gamed it out” a bit more.
What happens if Israel does hit the nuclear facilities? What’s the escalation after that?
