The Subtext Between the US and Iran

So, the first thing that pops up when I search “middle east” is… the US thanks Iran for swift release of 10 Navy sailors.  Apparently, the sailors’ boat broke down while training on the Gulf. From what I see, it looks like the sailors were doing nothing wrong, but they could have been spying. I don’t know. Iran officials apologized, and the US said it was okay. I can definitely see some tension here, like Castiel from Supernatural when he stands too close to Dean. On the surface, though, it seems fine. What do you think of the relationship between the US and Iran?
