Adam Ereli, a Middle East expert and former U.S. Ambassador to Bahrain, says this puts the U.S. in a delicate position.

“Let’s not forget our close and steadfast and important allies in the region who not only rely on us, but who we rely on for our national security," said Ereli.

Israel has threatened to bomb Iran if it gets too close to making a nuclear weapon, despite U.S. efforts to tone down the harsh rhetoric. Analysts don’t believe Israel will attack during negotiations between world powers and Iran.

But analyst Robert Satloff says Israel's impatience is growing.

“I think the likelihood of Israeli military action against Iran has gone way up," said Satloff.

Satloff says the current Israeli government feels it has been left out in the cold.

That could have a negative impact on the Middle East peace process, which the U.S. is spearheading.

“And that is because the crisis of confidence between the United States and Israel will have an impact on this diplomacy," said Satloff.

Looking away from the U.S., Netanyahu has met with the Presidents of France and Russia to appeal for tough terms on a nuclear accord with Iran.

Despite the deep disagreements with Netanyahu., Secretary of State John Kerry says the Obama administration will not let down its key ally.

“We believe deeply in our commitment to Israel, deeply, " said Kerry.
