I cannot bear [Israeli Prime Minister Benjamin] Netanyahu, he's a liar, French President Nicolas Sarkozy told U.S. President Barack Obama during the G20 Summit.

You're fed up with him, but I have to deal with him every day, Obama replied.

The dialogue took place during a private conversation between the two leaders in a meeting room in Cannes, France last week. Obama and Sarkozy were talking before a press conference, unaware that their microphones were on and broadcasting to a room full of waiting journalists.

French Web site Arrêt Sur Images first reported the remarks, which the journalists collectively agreed to ignore, due to the sensitive and private nature of the conversation, according to The Guardian.

Surely, both leaders are embarrassed about their disparaging comments about a key ally. The big question to come from this is will the remarks change Washington's relationship with Jerusalem at a time when Israel considers going to war?

Netanyahu and Israeli Defense Minister Ehud Barak have repeatedly pushed for Israel to launch a military strike against Iran.

Iran is thought to be developing nuclear weapons, which Israel considers a direct threat to its safety.

So far, the U.S. has remained quiet on the Iran issue, and the Obama administration is happy to wait until the International Atomic Energy Agency delivers its report on Iran's nuclear program this week. Obama's private comments during the G20 indicate that he couldn't fully be behind Israel's plans.

Iran believes that any strike from Israel would immediately invoke the U.S.' might, and President Mahmoud Ahmadinejad said that it would strike back against the U.S. and Israel.

In the overheard conversation last week, Obama also allegedly criticized Sarkozy for not informing the U.S. that France would vote in favor of Palestine joining UNESCO, the United Nations agency based in Paris that focuses on culture and education. Name-calling aside, this is proof of Obama's allegiance with Israel.

Neither the U.S., Sarkozy's office, nor the Israeli government have commented on the remarks.
