We did enough to meddle into their affairs in the past and the end result is what you see now. There is no business for the US to be there. Although... this development changes a lot. Honestly this is another Trump/Bolton/war hawk conservative fuck up. By canceling the nuclear deal the US has no other inroads to talk directly with higher up officials in Iran. Even if it didn't stop a missile program it would have built a bridge that would have given SOME access to the regime. Now we are only looking over the fence at them and our only voice is going to be our military. What a shit show of geopolitics we've been lead into thanks to Trump. This is what Christians want more of? I hope we send all their children to war because I'm not sending mine.
