I have no special insight into the workings of the Russian state, but I simply cannot believe this ship will stop and return home. This ship can be insured by a non-EU insurer, a Russian insurer or gain a Russian state certificate of cover / indemnity.

On a different, related theme - prompted by the possible despatch of troops to the Russian naval facility in Syria.

How many Russians are working in Syria, excluding diplomats? I would expect until recently families accompanied them, so are there signs of families leaving, or not returning after holidays?
