Hopefully the Cubans haven't stuck their financial neck out to far in anticipation of US tourism dollars.  With the Dumpster in charge it seems his favourite tactic is to wait until investments are half way and then to "re-negotiate' the terms in his favour.  He has said exactly this with the Keystone pipeline in that he wants a better deal for the US, ditto for NAFTA, etc.  His business history reveals the same pattern.   He will ruin the US reputation for rule of law and sticking to contracts or agreements made.  Nobody should trust the financial integrity of the US government with this financial delinquent in charge.
