It's not going to be an easy run. Korea has some fighters and AA missiles ready, so the losses would be significant on both sides. I bet they are now calculating if losing 50 planes is worth teaching Kim a lesson, because this bombing run will be nothing more than a smack in the cheek. They'd need weeks of constant bombing to completely disable Korea. IMO it's not worth it, but they won't come to an agreement because Kim is crazy and stubborn.
I don't agree with you. During the war in the Balkans as American planes were shot down? Serbia also had Russian air defense and fighter jets. Do not panic ahead of time. If we plan it right the first blow of the losses will be minimal.
