I guess, Leonardo, that you missed the point: Russia is NOT reopening that base in Cuba,so I think it's safe to say that Russians are NOT "back on Cuban soli".
But I decided to investigate a little.
What I found is that the "surprise" was initially published in the russian newspaper "Kommerzant", without any base. Then "The Nuevo Herald" published it as a "true" story. No matter for them that Putin himself has denied everything.
But he could be lying, of course. I don't trust him. Nevertheless, in this case I feel a great lot on certainity that he is saying the truth: I guess it could be difficult to reopen the facility, as it currently (since 2002) is the campus of the UCI (http://www.uci.cu/?q=historia).
Also, we must recall that BBC said, back in 2011, that China was using it: http://www.cubadebate.cu/noticias/2011/01/22/bbc-reabre-base-sovietica-en-cuba-y-la-pone-en-manos-de-china/#.U8e3vEBrzTo
BTW, Lourdes base worked (from 1967 to 2001) strictly under UN-created rules, as other stations all over the world, belonging to the USA, the UK, Australia, etc.
Even though I don't consider Wikipedia as a completely reliable source, I think the article about the 1962 crisis is sufficient as a starting point to find out what happened: "After the US had placed nuclear missiles in Turkey and Italy, aimed at Moscow, and the failed US attempt to overthrow the Cuban regime, in May 1962 Nikita Khrushchev proposed the idea of placing Soviet nuclear missiles in Cuba to deter any future invasion attempt."
Facts: after the removal of the soviet missiles, Kennedy pledged not to invade, or help someone to invade, Cuba (even though not enough on a firm way - check ttp://www.washingtonpost.com/wp-srv/inatl/longterm/cuba/stories/history010792.htm
). And the missiles in Turkey were removed in 1963.
Don't simply take my word for it, take Kennedy's: http://www.jfklibrary.org/JFK/JFK-in-History/Cuban-Missile-Crisis.aspx
. It might also be interesting to read about CIA involvment on the Bay of Pigs invasion (http://www.jfklibrary.org/JFK/JFK-in-History/The-Bay-of-Pigs.aspx
). Even the official US historian says interesting things: https://history.state.gov/milestones/1961-1968/cuban-missile-crisis
And to come back to the beginning, about Google censorship in Cuba: http://www.cubadebate.cu/noticias/2012/06/19/escandalosa-censura-de-google-a-cuba-medios-y-blogueros-de-la-isla-no-pueden-acceder-a-estadisticas/#.U8fEVEBrzTo
. And remember that more than 400 videos on Cubadebate's Youtube channel were blocked, supposedly because ONE person claimed right about ONE video. Check. It's a fact.
