Cuban immigration waves

I agree with this article in the Sun-Sentinal that when the Cuban government starts talking about easing emigration rules, then you need to pay close attention.  In the past, that was how Fidel Castro signalled that a) he wanted certain concessions from the United States; and b) if he didn't get them he would open the floodgates.  That happened in 1965, 1980, and 1994, so we are even slightly overdue.  There is no need for alarmism, but it has worked very well for Fidel Castro in the past.
