This won't happen. You forget what happened after the Spanish-American War 1898. Cuba wasn't annexed then ... it won't be now ... and for the same reasons.
Nox, what a bad post, first, what reasons are you talking about, I would like to know them, nevertheless, there is a big difference between the year 1898 and 2003, and that is the fact that there are more than 3 + million Cubans living in the United States, mostly Florida. Moreover, all of them can vote, in fact they have a great deal of political power within the Republican Party, in fact once Cuba is liberated, they are not going back and living behind all the benefits they enjoy in the US.
As result the only solution is to anexate Cuba to the US, being that one of the major differences in policy between the Cuban opposition whitin the US, and the opposition in Cuba, Cubans want Cuba to be an independent country, while the Cuabn exciles want Cuba to be anexated.
AmesMedio, in fact China has a great deal of interest in Cuba, after the russians left, the Chinise took over the intelligence stations in Cuba (satelites, radio stations) all at the aim of spying the US, thats something no many people knows, but the intelligence community is well aware of.
Nox, please dont put post just to contradict what I say, without even doing your homework first.
Did you know in Germany only born Germans are consider citizens, that is no immigrant is ever allowed to become citizen!!
