Why do people slam President Obama for lifting the restrictions on Cuba?

Commies, I hid under my desk at school from a commie nuclear attack in the 50's, I went to Vietnam in the 60,s, watched protest against them in the 70's, seen their so called defeat in the 80's, and to this day I wouldn't recognize one if he stood in front of me. Cubans are just folk like us and we should have normal relations with them. To hell with Castro and his little bro. They are the remnants of a 50 year old pissin match. Obama is a modern progressive man that is on the ball.
