No shit. Trump pulled us out of the mutually-beneficial nuclear deal that Iran had been abiding by simply because it was brokered by democrats. Ukraine gave up their nukes in exchange for security guarantees from us, the UK and Russia... We all see how well that worked out.
Well no shit. Countries with nukes aren't likely to be invaded or bombed. I bet Ukraine is kicking themselves for getting rid of the ones they had. I wouldn't be surprised if this kick-starts a new wave of nuclear proliferation, and I can't say I'd blame those countries.
I think it'll strengthen everyone's nuclear resolve. Strategic ambiguity (with the common knowledge that you are a nuclear state, like Israel) is pretty much the only option now.
Iran was playing the game of "we aren't a nuclear power, but we COULD be" wasn't enough. Everyone sees that now. The only real deterrent is a literal nuke, now.
What resolve? They already have nukes, they show no signs of wanting to use them, and consistently want to be left alone to do their thing.
I hate when all the news bring up a completely unrelated country all of a sudden. Makes me think this WWIII thing is going to happen and is being pushed for.
