It’s hard to imagine Un being stupid enough to start a war with us. But..
Something to think about.
Our ‘leader’ will be very reluctant to strike back and when he does it will be a measured response. IOW chickensh__.
Also, with S.Korea only a few miles away some restraint will be a must.
IMO we would use nukes as an absolute last resort, even if Un used one first.
And with his military in hardened caves conventional weapons may be ineffective.
Intersting Peter King was talking preemption in NK just yesterday... I think the US would strike any Nork ICBM on the pad if necessary, the sites are heavily defended but cruise missiles and B2s ought to be able to pull it off
