Hmmm... Cuban Communism will not outlast Fidel, eh?
they'll try to keep communism afloat in cuba, of course, but it just won't work... the Cubans have suffered long enough and know exactly what the score is. remember that just 90 miles away live their brothers, daughters and relatives under freedom and liberty, so from their relatives they get the truth, also from radio and clandestine television signals from florida
Cubans are a proud folk (deservedly so: all the ones i've met are very talented people) but i think they have just about had enough. when the change comes it will be spectacular, just as it was in eastern europe and in russia.
one needs to remain optimistic and at the same time actively work towards this goal.
