More proxy asymmetrical warfare using separate groups to injure the other side. The Saudi's will focus in economic warfare against the Mullahs and the Mullahs will continue trying to destabilize the Saudi royal family by bringing arab spring to the Kingdom.

I wouldn't be surprised if we never hear about the Israeli's working with the Saudi's to neutralize Iran's nuclear program. I have no hope that there will be any official assistance provided to any of our allies in the region. At least not till late January 2017.

Unlike the Hermit Kingdom, which is essentially the yappy but useful little dog of the the regime in Beijing, Tehran and Riyadh have enough independence to start and stop their own trouble making whenever they want to. For the foreseeable future, the US will continue to support the House of Saud, IMO.
