The Russians can detonate the nuke in one of their drone subs and cause the same damage, pretty much anywhere on the East Coast, or the West Coast.
Hmmm, come to think of it...
You mean several billion dollars of improvement?
The Russians don't need a nuke. We've got AOC on the loose. Takes a little longer, but there's no risk of retaliation unless what's left of America wants to nuke Brooklyn.
