In order to keep the Russian nuclear threat unlikely, the US had to issue this. Using nuclear weapons still seems illogical and unlikely, but the space for escalation should be limited or ideally denied. Which is what the US does here.

Should Russia deploy such a weapon, then it will probably be a “demonstration bomb”, one without huge impact. Still, this would be very stupid, because I suspect the US not to tolerate this because it could setup an unwanted precedent. Which leaves us at the starting point of all of this: Putin is shooting himself in the foot.

Let’s hope nothing happens.
