NATO didn’t salvage the Kursk; two Dutch companies, Mammoet and Smit International did.
Yes, but the first divers on the wreck were Norwegians. I've been told by a buddy of mine who is a former RN diver that this was a fig leaf. Several of the first divers on the Kursk were actually RN divers. Friends of his.
The Russians didn't want to be seen cooperating with a foreign Navy, I guess.
And the Dutch are members of what international military organization?
