How can we get a carrier group into the Black Sea and hold it?
Not the same as Cuba or the South American countries. Though the fact we let them slide away is very dangerous.
I wouldn’t advise that either due to local Russian air superiority. But the same applies to the Russian fleet: the Black Sea isn’t that big: 243 miles from Constanta Romania to Sevastopol, probably about the same from the Turkish coast or Odessa in Ukraine.
