The Interpreter has a long tortured analogy involving dorm RAs to explain why this is about the US. Here's a shorter one: all parties under discussion had back channel connections to the US. Now they don't. We used to mediate. Now we don't. So now the Iranians and Qataris are swapping towns and ransoms and shit instead of negotiating through backchannels.
Worthy of note: Arab royalty is bugshit about houbara bustards. Saudi Aramco World runs an article on the damn things and the nobility of falconry like every eighth issue. And, since falconry for bustards involves assloads of kit in scary-ass locations, a typical adventure might involve 150 guys, three dozen landrovers and all the shit you need for two weeks in the Panjshir.
After which point you leave all your shit there for the Taliban and get back on the G650.
Multiple times a year.
Allahu Akbar.
