I hope that, between the nuclear treaty and Daesh providing a common foe, we can start making more political inroads between western powers and Iran... maybe even Lebanon, too (the Beirut bombings are fresh in memory).

The hard part will, of course, be Israel's influence on western politics, since the situation is worsening there with the recent spate of stabbings and the new walls going up to protect settlements in the west bank.

With Iran and Lebanon's ties to Hezbollah, Israel will (quite reasonably, all things considered) react badly to inroads made between these countries and Israel's allies.
