There were reports, even from a sailor aboard one of those escorts, that state a small fire broke out on Moskva
There are all sorts of reports circulating around.....
It would be pretty hard to repair the damage decribed in a couple of days....as mentioned in previous posts the "Moskva" is currently on patrol once again which suggests she's in good condition.
I guess the main reason is that the US wants to give those goods directly to the Georgians themselves, and not via the Russians, wich are in Poti.
It's possible....but when they announced they were docking in Poti, they knew the Russians were there (and most likely would be there) already
