You are making up a straw man.
The economic blockade by the US has the goal of destroying the political and economic order of Cuba. And just to be clear, this blockade is not just blocking Cuba from trading with the US but is effectively blocking Cuba from a good portion of the world market except for a few small allies. And even those trades with allies can become vastly more costly because of the blockade.
There are not many countries that would survive such a blockade not to mention thrive in it.
Are there internal problems in Cuba? Sure there are. Does it make my quoted sentence incorrect that said:
>Of course because of the economic blockade against Cuba they are forced to be creative on how to use the available resources.
No, it does not. It does not state that there might not be also other problems in Cuba.
There is lots of internal problems one can talk about and if someone has honest questions, please ask.
Just don't use these internal problems to minimize the injustice of the blockade against Cuba. (Not to imply whether this is what my former poster intended to do or not).
