Multilateral negotiations have positive results. Pressure from strong states with ties to Iran, such as Russia and China, as well as friendly gestures from traditionally wary regional states, such as Iraq and Bahrain, convince Iran to back down from its public stance. Iran and Israel agree to refrain from any major nuclear tests, and both sides agree to strategic arms limitation talks.
Additionally, Israel agrees to return to the negotiating table with Palestine (due in part to strong US pressure) and Iran agrees to urge Palestine and other neighbors to welcome a two-state solution.
While the outcome remains to be seen, it is possible that Germany's leadership has turned a possibly disastrous situation into one with potential for lasting positive consequences for peace in the Middle East.
