Yeah, the story strikes me as a bit of a nothing burger. Navies have tankers. Ships need to refuel while at sea. This is not new.
Perhaps the Russians do have a bit of a logistical issue in this case, but I agree that a diesel tanker is probably headed to them now. That’s why diesel tankers exist.
It’s not like the task force will just drift aimlessly until it is dashed on the rocks of Morocco. They will be fine.
There was a story a day or two ago that they were anchored somewhere, refueling from tankers. The uke site is behind.
