The situations in Venezuela and Zimbabwe are so interesting! Will the presidents/communists in power really make any concessions? What will happen when castro finally dies, I wonder?
I believe Castro, whose fingerprints are on many places, including Zimbabwe and Venezuela, is trying to consolidate the countries in this hemisphere using Chavez and his oil producing country Venezuela, as his powerbase.
The African nations were ripe for communist dictatorships and that too can be credited to Castro support and personnel. Of course Castro, Chavez, Mugabe, et al have support from within the United States, either through socialist ideology or ignorance.
