I am not sure if he really is free? Just because he is now out of jail, does this mean, the ones who got him in jail in the first place are fine of him being actually be free?

Because of mainly corrupt world politics, I think he is not really free. He has to watch out what he says, where he goes and the same is true for his family. Remember, the US politicians invade entire countries and dictate what to do there. 

Also, you say it took him 14 years to be released. Why was he even in jail? Why did it take 14 whole years to get him seemingly out of it? The answers to these questions give hints about how Julian might have to live his life.
