Right, but they're moving ships, including the third and final "big iron" missile cruiser out of Crimea into the Mediterranean, that's not a weekend trip.

I.e. moving it from the one place where it could support a Russian invasion to one where it can't.

This isn't done for no reason. They outright stated that the increased and unprecedented activity in the region by NATO ships and provocations like what happened with the US destroyer (USS Porter?) required a response so that the NATO ships wouldn't feel safe. And it's also training for a seemingly probable future conflict by the most critical line of defense against US force projection Russia has.

Like if those three ships are enough to sink a US carrier or two, the US is never sending carriers within 500 miles of their location.
