The idea that you could nuke a city to kill the entire population but leave the buildings there to be occupied is absurd. Assume if we unleash that we will be attacked with everything they have including ICBMs. There would be no US military left to occupy that neutron bombed city. It was scary but I think pointless. Maybe if nobody else had nukes it made sense but once we were facing adversaries with them, forget it.
Which is precisely why Liz Truss and her dopey EU counterparts would be open to it.
Just look at the self satisfied smirk on this dolt's face.
