The problem is that they were NOT treated well. Pointing guns at people and taking them prisoner through no fault of their own isn't being treated fairly. Even Joe Biden said so, you lefties can't find your asses in a phone booth! The fact is we are giving Iran billions of our dollars AFTER giving them all they wanted with the nuke deal, all so obama can claim victory and they very likely won't change a damn thing.
The US is acting like the rich fat man that routinely gets slapped around and fleeced and thanks the mugger for not hurting him.
We would be pointing guns at them if the situation were reversed.
And, for the millionth time, it wasn't our money. If we decided to keep it we would be breaking the law.
The thing that Iran did that wasn't cool was broadcasting images of our sailors on their national tv. That being said, this was ultimately a positive interaction with Iran compared to earlier. It's called progress...unless you just want war then you lost.
