Kerry's an ass.
But much like Glastnost, I fully believe the best and fastest way to bring down Cuba is open it up to Western, modern influences. The Cubans love us, and a quick interjection of some imperialistic capitalist green will only bolster that.
Do not hope for change.
Cuba uses a monetary unit called a peso. But what they use for their trade is what has actual value, and the countries that trade with Cuba use it, but within Cuba its use is exclusively governmental. The people there are paid in pesos, but it isn't the same peso that the govt. uses. This .... "peoples' peso", if you will, is almost totally devoid of value, thus keeping the Cubans in poverty and under the thumb of their communist overlords.
Until this situation is rectified, trading with America will not enrich Cuba or help the Cuban people at all.
It will be of some help to the Cuban government .... which has been struggling since the demise of the USSR and its benevolent underwriting of the Cuban economy.
Cuba has been trading with Canada, Great Britain, and many other countries for a long time, and this has not served to enrich the Cuban people.
Now America is a great country, as we all know. I love America! But, really, if the rest of the world trading with Cuba doesn't help the Cubans, do you think adding America into the mix will really help anything?
All Obama has done is to help shim-up a hurting Commie government ..... nothing else.
