There are international laws regarding maritime salvage that apply here. This is an interesting incident that brought to light early US deep recovery capability - which in 1966 were still a clusterfuck. But they got what they were after. 1966 Palomares B-52 crash - Wikipedia I'd be surprised if Russia or anybody else has the capability to retrieve this thing. But, who the hell knows. Even if they find it first I bet we have ways of destroying it Incidentally, the takeaway from the Palomares link would be the name John P Craven. He has passed away, but if you were ever looking for the government's Chief Scientist Who Knows Things - really Knows Things, that would have been the man.
