There is an obvious campaign taking place to white-wash Iran and portray their islamist leaders as some sort of amicable and moderate government. The deal is signed now it's time fro Washitgton to save face. The marching orders have been given to the press to suppress negative reporting on Iran and keep pumping up everything negative on Russia, Syria and Saudi's. I suspect Washington is trying to distance themselves from Saudi regime, although Washitgton really has nowhere to pivot they will muddle through ME creating more and more costly mistakes.
US economy is a toast another recession is coming, dry shipping in Atlantic, Baltic,Pacific is at the levels of 1980s. Dollar is as strong as ever.
Russia will have to pump more oil to make up budget and that will damage US/Saudi oil industry even more since their currencies are staying strong. Saudis will get desperate pretty soon. Iran will probably suspend its membership in OPEC and pumps oil like madmen.
Let's see in 6 months if I am wrong.
