why doesn't Obama do something about american prisoners in foreign countries?

an excerpt from Trickle Down Tyranny about Alan Gross:

in December, 2009, before he was able to take the next step - linking the Cuban Jews to the outside world - he was arrested. the Cuban authorities phoned his hotel room and asked him to come down to the lobby to pick up a message. instead, the secret police picked him up.

for the next 14 months, he was held in a maximum security prison. he kept asking what crime he had committed or what the charges were against him. there were none. they were simply holding him.

the little food he got in prison was tainted, and Gross became very ill. when judy, his wife of 40 years, was finally allowed to see him, in july 2010, she was shocked. he had lost 90 pounds. he wasn't heavy to begin with. only when the cuban authorities believed that he would die soon was he moved to a military prison hospital, where he received some help.

in February 2011, Gross's Cuban attorney came to visit him. he was surprised and grateful that the american was still alive. he said he had good news.

you'll never guess what the "good news" was.

the Cuban communists had decided to put him on trial. he was charged with being a spy and committing "crimes against the state of Cuba."

why was that good news?

there was a slim possibility that he might be found innocent and released. could that happen? his Cuban attorney, perhaps wanting to be kind, said, "it could."

but it didn't.

in a trial closed to the american press, the prosecutor said Gross was a "mercenary" sent to Cuba to wage a "cyberwar" against the Cuban revolution. ordinary Cubans are not allowed access to the internet and giving it to them was a "counterrevolutionary" act.

the judge sentenced Gross to 15 years prison. Gross is now 61 and will likely die before he is released. after his arrest, his 26-year-old daughter was diagnosed with cancer. he may never see her again.

where was Barack Obama when all this was going on?

Playing golf, going on vacations, and ignoring what was going on in Cuba.

throughout Gross's long ordeal and travesty of justice, Obama didn't utter a single word in his support.

...

so my question is:

why does Obama and his team have so much compassion for the terrorists held in a U.S. navy base on one side of Cuba and no compassion at all for an American held on the other side of the island?
