So easy to say, hard to do. And it’s hard to say that threatening to nuke everyone is going to apply the right kind of leverage, if say India is already starting to drown. Wouldn’t it be better for everyone else then to take their nukes (or nuke them in advance) and let them drown?
Even if others haven’t gotten that far in their line of thinking, I’m guessing India sure has.
The CFC coalition was nothing compared to what will be required to deal with this situation - and notably, the CFC issue still isn’t really solved. Just mostly under control.
We’ll see how this plays out.
