Christopher Hitchens attempts to answer the question:
Fidel Castro has devoted the last 50 years to two causes: first, his own enshrinement as an immortal icon, and second, the unbending allegiance of Cuba to the Moscow line. Now, black-cowled Orthodox “metropolitans” line up to shake his hand, and the Putin-Medvedev regime brandishes its missile threats against the young Obama as Nikita Khrushchev once did against the young Kennedy. The ideology of Moscow doesn’t much matter as long as it is anti-American, and the Russian Orthodox Church has been Putin’s most devoted and reliable ally in his re-creation of an old-style Russian imperialism. If you want to see how far things have gone, take a look at the photograph of President Dmitry Medvedev’s inauguration, as he kisses the holy icon held by the clerical chief. Putin and Medvedev have made it clear that they want to reinstate Cuba’s role in the hemisphere, if only as a bore and nuisance for as long as its military dictatorship can be made to last. Castro’s apparent deathbed conversion to a religion with no Cuban adherents is the seal on this gruesome pact. How very appropriate.
What ? You didn’t believe that Castro was sincere, did you ?
