Well he sent them millions of dollars to suck up to his supporters, Cuba is such a basket case it means nothing but buys Carney votes. I don't think Carney sent them oil, could be wrong, but Trump has said that he will allow American companies to send American oil to private companies in Cuba, which sounds like a "friendly" take-over push, but in a communist country the government can take what it wants I have no idea how that would work, guess we'll see.
