There's a saying I heard from my granpa that says: "Mal le paga el Diablo a quien le sirve", something like "the devil pays poorly to those who serve him well"

Rubio is there to topple the Cuban Revolution, they know they will need to do it on the first two years, otherwise they might not have another chance

I'm afraid not, Rubio's appointment is to ignite a new interference and possible invasion of Cuba to take down the Revolution, they know they have to do it in the first 2 years of Trump, otherwise they might not get another chance in a generation, Cuba's economy is basically stalled now
