Well, here's how I see it.
The European market [I]has so far[/I] been keeping Cuba afloat.... Because of the American embargo.
When an ungodly monster consumer oriented capitolist beast market like the US is a mere 80 miles from your shores, it is enough to support any nation 5 times the size of Cuba.
Remember. They have I think 6 Million People, all living under Commiunism?
We have 265,000,000 hungry capitolists that would love to have a summerhome on an Island, or smoke a fine Cigar, or fuck a fine $25.00 whore. All a mere hand full of miles away.
Cuba will act as a lynchpin between Euro-US commerce, with both parties pouring $$$ into the Cuban system to gain control of it's rescources, and revenues.But I think distance is a critical factor.
We can sail barges and supplies and goods to Cuba cheaper, since we are closer then Europe.
We can fly people in and out of Cuba cheaper, since we are closer, and we can import Cuban goods cheaper, since we are closer.
Being closer means a more efficient way to get things done cheaper, and that's why all your Cuba belongs to the US.
