Post World War II power balance between Zionist Israel and Arab-Persian Muslim countries, who considered Israel as a “pushed in state” in Middle East, is now being replaced in the post-Iran treaty era by an emerging strategic balance between Iran on one side, and Israel plus Gulf Arab countries on the other side.

From the Iranian perspective, optimists see Iran's gains in a number of ways. The ailing economy of Iran which was caused by western sanctions will now get a chance to improve.

Bridging the gap between Iran and the West would help soften Iran's present voice against Israel through a possible political and social transformation in favour of the West.
