We may be getting closer to that Guantanamo "theme park" memorializing the USA's descent as a sovereign power under the globalizing influence of Pentagon-style capitalism aka "cowardly capitalism" based on "cost plus" defense contracts.
The mercenary industry became a boom sector, organized around the Goon Belt (WDC). Neocons ruled. America suffered a huge loss in respect as the rest of the world watched aghast at its wild antics.
Lots of giant corporations were never fans of the Neocons however and getting funding for such a theme park need not be a huge problem, especially if it's established as a non-profit.
The Cubans should not have to worry about coughing up the dough. They weren't the cause of the problem and needn't pay the tab for the cleanup, which will take decades.
