Russia and Israel have a long history of diplomatic and military collaboration in the Middle East, dating back to the Arab-Israeli war of 1948, when Israel's triumph over its neighbors was largely attributable to Moscow's military support.
The American public has had enough of wars, doesn't know what to believe when politicians speak, and is more interested in taking care of things at home. This is not likely to change when the next president takes office, and Clinton and Trump know it.
I've had the opportunity to conduct public opinion polls across the Middle East in order to provide content for policy discussions at the UAE's annual Sir Bani Yas Forum. We surveyed over 7,400 adults in six Arab countries (Egypt, Lebanon, Jordan, Iraq, Saudi Arabia, and the UAE), Turkey, and Iran.
The conflicts in Syria, Iraq and Yemen cannot be resolved unless Iran is at the negotiating table.
Amidst the background of a violent conflict that is destroying Yemen, the UAE seeks to prove to the world that the wealthy emirates are capable of more than just spending billions of dollars to create a first-rate military with advanced weaponry.
Now that a Senate minority has blocked the bipartisan majority from an up-or-down vote on arguably the most significant foreign policy measure in a generation, some in the media are rushing to judgment about winners and losers.
If GCC officials slowly pivot toward the perception that their long-term interests reside in an improved relationship toward Iran, such a strategic shift would be seen in Riyadh as an erosion of GCC unity against an emboldened Iran.
You can't always get what you want. (That's why it's called "negotiation"...)
The most tragic consequence of Congress killing the deal would be that it would eliminate the prospect for greater U.S.-Iran cooperation in the region on areas of mutual concern. It would lock in continued enmity between the United States and Iran, serving only to exacerbate tension and conflict across the Middle East. To go down this path when such a mutually advantageous alternative exists would truly be a blunder of historic proportions.
