In a separate appeal to American Jews, Israeli Prime Minister Benjamin Netanyahu, a fierce opponent of the July 14 accord, pushed back in a webcast on Tuesday against the Obama administration's argument that the agreement was the only way to avoid eventual war with Iran.
The Republican-led US House of Representatives will vote on whether to reject the agreement when lawmakers return to Washington in September, party leaders said on Tuesday, setting up a showdown with the president.

Greg Rosenbaum, one of 20 Jewish leaders who met Obama at the White Houseon Tuesday, said on Israel Radio that the president spelled out what exercising a US military option to strike Iran's nuclear facilities would mean if the deal between world powers and Tehran was scrapped.
"He said military action by the United States against Iran's nuclear facilities is not going to result in Iran deciding to have a full-fledged war with the United States," Rosenbaum, of the National Jewish Democratic Council, quoted Obama as telling the forum.
" You'll see Hezbollah rockets falling on Tel Aviv.' This is what he said would happen if the US had a military strike on Iran," Rosenbaum said, referring to the Lebanese Hezbollah Movement and Iran's long-range missile.
