The U.S. had laid out restrictions on the Cuba embargo and we are not going to lift it until the have an independent judiciary, free elections, the Castro brothers agree, and they release all political prisoners. By lifting the embargo before Cuba meets our demands its a form of appeasement because we are giving in. Appeasing Cuba makes us look weak and could cost us credibility, but losing credibility has nothing to do with proliferation. Proliferation would happen fairly quickly if we lift the embargo with Cuba. The probability of countries attacking us for lifting the embargo with Cuba is very likely because they would want us to lift the embargo with the too. For example, North Korea and Iran. This problem is big because it could escalate to a world war.
the embargo has been around since the early 60s I, since living in Miami, can tell from personal experience that the embargo is a failure.
The embargo is only starving Cubans, creating mass deportations of the populace, and hasn't weaken the gov't to collapse. The best solution is to meet with them and have a negotiation to democratize Cuba and fix relations. All they want is to not be treated as an inferior nation but equal, continue the payment of gitmo, and they will open elections, and pay the reparations of the loss of money
America looking weak??? Are you kidding me??? if anything it would mean America recognized it's failure will will be willing to pursue a path to peace and will in fact have a positive influence in the world. BTW the only reason why we started to uplift some restrictions is because Raul Castro has allowed one party elections in every position including his and as well as term limits so he'll leave office in 2016!!! Raul has even allowed some small business to open up in Cuba and allowed Cuban people from Miami to visit family back home in Cuba. So taking everything in consideration don't try to make up some Fox news bs about the world!!!
