“The American public is becoming less inclined to believe the one-sided position, pro-Zionist position that’s been thrust upon the public for so long,” Steven D. Kelley told Press TV on Saturday.

He also said that recent remarks by President Barack Obama that “we’re all pro-Israel,” are aimed at appeasing Israel over the Iran deal.

On Friday, Obama said he is committed to maintaining Israel's military edge in the region, during a webcast hosted by the Jewish Federations of North America and the Conference of Presidents of Major American Jewish Organizations.

Obama has taken a “diplomatic position to certainly placate the Israelis as well as the Christian Zionists here in the United States that have been making so much noise and opposition,” Kelley noted.

“But I think that there is still a very good possibility that the majority of this country will go along with this,” he opined.

Iran and the P5+1 group of countries - the US, Britain, France, Russia, China, and Germany – announced the conclusion of nuclear negotiations in the Austrian capital, Vienna, on July 14.

Israel and its supporters in the US have launched a massive campaign to defeat the historic agreement in Congress.

“We do have to be concerned, this is a dangerous time, we have to worry about a possible preemptive strike coming from Israel who is certainly feeling very humiliated over this deal” and some other issues, Kelly observed.
