I can't see NATO countries being on board with any intervention. This is being driven out of SArabia and Israel and a lesser extent UAE, and indeed by war hawks like Bolton. Pompeo is making ludicrous connections to unrelated events to build a case for war when there isn;t any to speak of.What would be really interesting is if the rest of NATO doesn't back America.
UK, France and Germany have already started keeping distance by sticking to the nuclear deal.
ISIS in Iraq (UK) and Syria (France) were a bit different because of old colonial ties to those countries. But Iran was never colonised so there's no 'sphere of influence' reason for either to get involved at all.
The one thing that doesn't line up is that Russia is an Iranian ally and has such a sway over Trump I can't see him pulling the trigger. Who knows with him though.
