4 Russian supply Ships are believed to be en-route to Venezuela.

Also there are reports that 4 Russian Submarines are in the region,off the coast of Southern Cuba.

Russia has vowed to defend its Venezuelan oil interests in the strongest possible way within the boundaries of international law.

I think the situation in Venezuela needs bringing to a climax before the Russians can mobilize any sort of response on the ground.Russia needs to be marganlized. The sooner Maduro is dead the better.Once Maduro is out the way Russia has no business being anywhere near Venezuela.The Russians will have to go the legal way through international courts of arbitration to try recover any investments.Emphasis on "try".Guaido can say any previous debt is none binding.US courts are seeking to recover 10 Billion from Maduro regime.
