U.S.-Israel rift exposed by Iran talks in Geneva

They came pretty close. From all accounts, a deal between world powers and Iran over Tehran's nuclear program was nearly reached. In the end, there was no final agreement after three days of high-level talks in Geneva over the weekend but it did expose a growing rift between the United States and Israel.

As the momentumwas building late last weekfor an agreement that could have temporarily curbed Iran's nuclear program and offered relief from sanctions, Israel's Prime Minister BenjaminNetanyahutold reporters that this, for Iran, was "the deal of the century," and a "very, very bad deal." That deal, of course, was never signed. (More talks are expected later this month.)

• INTERACTIVE: Iran at the crossroads

Netanyahu is famous for his fiery rhetoric especially when it comes to Iran. Remember that cartoonish drawing of a bomb that he brought to the United Nations just over a year ago. The prime minister drew a red line right through it, to highlight Israel's opposition to Iran's nuclear program.

His tough talk about Iran has largely been welcomed by many Israelis, who view Iran as a threat to their country's existence. But it seems to have stuck a nerve with the top U.S. diplomat. The relationship between Netanyahu and U.S. Secretary of State John Kerry, it seems, has turned frosty.

Kerry took aim at Netanyahu's "deal of the century" comments, saying yesterday, "the time to oppose [a deal with Iran] is when you see what it is, not to oppose the effort to find out what is possible."

And it's not just Iran that is behind the chill in relations between Israel and its most important ally, the United States.

Kerry, while on a visit to Israel and the West Bank last week, was critical of Israeli policies, warning that if the current round of peace talks fails, Israel could see a third uprising, or Intifada, and increasedinternational isolation.

"The alternative to getting back to the talks is the potential of chaos," he told a joint Israeli and Palestinian TV interview.

'No personal clash'

The U.S. ambassador to Israel,Dan Shapiro, tried to play down therift, saying "there's no personal clash" between his bossKerryand Netanyahu. Shapiro told Israel's Channel 10 News the two are friends and have "worked well together before and are continuing to work well together."

The relationship between the Obama White House and the prime minister's residence in Jerusalem has not been seen as overly warm since Obama was sworn in. In fact, Obama was reported to be furious that Netanyahu seemed to picked sides the Republican side in the last U.S. presidential election campaign. Still, Obama made his first foreign trip of his second term to Israel, to mend fences.

For now though, the Israeli media are having a field day in writing about the chill in relations.

"If there was a synoptic map for diplomatic storms, the National Weather Service would put a hurricane warning right now," wrote Chemi Shalev of the left-leaning Israeli newspaper Haaretz.
