" I am sure Cuba is not checking tourists laptops and cell phones same with Russia."

Haven't been to Russia lately, have you?

Though the Russian dictatorship does tend to focus on checking the laptops of their own citizens primarily, particularly those who might be brave enough to criticize Putin. 

As for Snowden, he's just a sock puppet for the Russian dictatorship.

Your naivete about the world outside of North America is charming.
