You’ve proved my point enough, I think.
“Russia has agreed to lend Venezuela over $2bn (£1.2bn) to buy weapons, President Hugo Chavez has said.”

“...the stage was set for one of the biggest lines of credit for oil-rich Venezuela to buy Russian military hardware. Up to $800 million of credit is available for Venezuelan arms buying in Moscow.”
You appear to be right on that one point regarding the Russia to Venezuela sub deal. But you also seemed to be trying to minimize the overall threat posed by Russia arming Venezuela.
To your point about the subs...
"...for what it's worth, Canadian defence reporter Dave Pugliese passes along a report that the planned sale of Russian nuclear submarines to Venezuela was scuppered after Hugo Chavez's bodyguards mixed it up with some Russian sailors:
...the KILOs (the subs) destined for Vietnam were originally to be purchased by Venezuela but that deal collapsed after a fistfight on board the Russian cruiser “Peter the Great” when it and other warships were visiting Venezuela.
Venezuela’s leader Chavez was in the process of visiting the Russian flotilla but his bodyguards were prevented from boarding. A fistfight then broke out between the Russian sailors and the bodyguards. The nose of one Russian was broken.
That ended the sub purchase.
Robert Farley notes that the deal is indeed off, and it's certainly not out of the question that the fight took place. But it's likely that the bigger reason Chavez balked at the deal is that his government is low on oil money these days.
