A pro-Israel organization argued Wednesday that a majority of Americans would support military action against Iran under certain circumstances, in a rare concurrence of message between some Democrats and Republicans at the Democratic National Convention.

Democratic pollster Stan Greenberg and Republican pollster Frank Luntz joined under the banner of the Israel Project to release data from a poll of voters in the United States, Great Britain, and Germany. They aimed to make the case that a U.S. consensus exists on Iran’s regime and the need for tough measures to combat it.

The Israel Project officials say the group is pushing for a diplomatic approach to dealing with Iran. But they prominently presented data portraying that a majority of Americans could eventually get behind an Israeli or U.S. strike on Iranian nuclear facilities.

“63 percent of U.S. voters support military action against Iran if diplomacy fails,” read the headline of the press release distributed during the event.

The Israel Project used the Wednesday event to kick off a national ad blitz aimed at publicizing the nuclear threat from Iran.

The pollsters said European countries are less supportive of Israel and less willing to contemplate military action or even economic sanctions against Iran.

“The Germans oppose military action for historical and cultural reasons and the British do not want another Iraq,” Greenberg said, “Yet the American are more open to military action, especially if a diplomatic solution fails to become a reality.”

Support for Israel

Obama’s support for Israel and popularity among Jewish voters has been an issue in this election season, and he has made great efforts to reassure that demographic that his support for the Jewish state is solid.

Rep. Robert Wexler , D-Fla., focused on that point for the totality of his floor speech early Wednesday evening.

“In his heart, in his gut, Barack Obama stands with Israel. Not only his words, but his deeds, bear testament to this fact,” said Wexler, adding, “ John McCain offers more of the same failed policies that endanger both America and Israel.”
