Cuba will sell its products to the US. American products will be seized as contraband and the people bringing those products in will be arrested as Alan Gross was arrested.
Such an imagination!

Have you found Raul Castro's statement about no trade treaty yet? If you can't provide a link, you probably shouldn't be presenting this as a fact.
What part of Castro saying Cuba will continue to remain a communist country are you not getting?
That means if any trade happens with the USA, the government will control and distribute. That is not free trade.
The government of Cuba has made cell phones for the people of Cuba illegal and the press and the internet is controlled by the government.
China and the USA has been doing trade and business with each other for about 42 years and China is still a Communist country.
Both countries are Communists and will remain communists, trade or no trade, so the Dems who think that will change in Cuba is not dealing with reality.
I don't believe anyone included free trade into the equation. I do however suggest you read;
How China Became Capitalist
How China Became Capitalist Cato Institute
Please note in the article; "The Party has distanced itself from radical ideology; it is no longer communist except in name. In recent years, the internet has increasingly empowered the Chinese to exercise their political voice. Nonetheless, China remains ruled by a single political party".
Is the conservative Cato Institute also not dealing with reality?
Can you name a country who hasn't loosened up the state's restrictions on it's society? Capitalism has a very impressive track record for bringing much more freedom to once suppressed societies around the world. Maybe you should read Milton Friedman's "Capitalism and Freedom".
Also, cell phones are no longer illegal in Cuba since 2008, There are one million cell phone in Cuba. They are expensive because of the lack of infrastructure, which off course would improve greatly if the embargo was lifted.
The cell phones are still controlled by the government.
US secretly created Cuban Twitter to stir unrest
USAID says the program ended when the money ran out.
In response, Josefina Vidal, director of U.S. affairs at Cuba's Foreign Ministry, said late Thursday that the ZunZuneo program "shows once again that the United States government has not renounced its plans of subversion against Cuba, which have as their aim the creation of situations of destabilization in our country to create changes in the public order and toward which it continues to devote multimillion-dollar budgets each year."
"The government of the United States must respect international law and the goals and principles of the United Nations charter and, therefore, cease its illegal and clandestine actions against Cuba, which are rejected by the Cuban people and international public opinion," the statement said.
The former web domain is now a placeholder, for sale for $299. The registration for MovilChat, the Cayman Islands front company, was set to expire on March 31.
In Cuba, nothing has come close to replacing it. Internet service still is restricted.
