Actually US warships are now plying the waters of the Black sea. Many US warships, tho the number is unknown. But what is known is that we now hold the balance of naval power in the black sea, and that a NATO ally decides who can and cannot get in and out of it.
So again...a message to the Russians. This message is we can blow your navy up if we decide to and dont think you hold all the cards in the region because you dont.
And as if the USN wasn't a bad enough foe to reckon with. There is also a ton of naval talent in NATO. Most of all the Brits, and of course the bloody Huns invented underwater warfare, but also countries like Norway have a lot of submarine talent. Others, like Turkey, Spain, Italy, Portugal, Greece, should they find the guts to fight, have all pretty good NATO standard equipment.
Remember were talking "NATO standard" not "Russian standard". And I purposely left out Canada because even if they still have some ground units with guts their navy has been eviscerated by their need to build a socialist paradise to the north of their sub-human masters. They have no submarines anymore and the entire navy, for that huge coastline, consists of a few rust bucket frigates and ice breakers. I dont even think they call it a navy anymore.
In short, their navy sucks. But there is a lot of talent in NATO to draw from and this entire Russia thing must stay a NATO operation. The last thing we need is to make unilateral decisions in Europe. Even if all the worlds oceans are basically USN lakes.
