Really?
Unless those B-52s are equipped with nuke cruise missiles, I would not send them to S. Korea.
There’s a B52 base a few miles down the road, the local news paper usually has stories about their deployment. Nothing yet about Korea, however there is a flock of them going to the Middle East for the first time in 12 years.
There’s not that many of them left, as compared to the Cold War days. I suspect there’d be lotsa work keeping up with multiple deployments.
