The NK are constantly in a state of war, comms being cut is probably a go ahead to fire.
We aren’t going to use any nukes or neutron bombs(which we aren’t supposed to have) in a pre-emptive strike. There’s just no way, that would be monumentally stupid and a great way to lose support world-wide.
Let’s discuss practical solutions.
The only way a pre-emptive strike will be worth it is somehow getting rid of all the artillery before any of it can fire.
I don’t think it’s possible to do a pre-emptive strike using conventional means on NK without Seoul getting battered.
I honestly think Kim is insane, he’ll feel like he has nothing to lose. Either we solve this diplomatically through China, or there will be war on the Korean peninsula and it won’t be like Iraq or Afghanistan.
In the long run war might be the way to go.
NK needs to be removed as a threat to peace.
