French President Nicolas Sarkozy told U.S. President Barack Obama last week he was fed up with dealing with Israeli Prime Minister Benjamin Netanyahu and considered him a liar. Sarkozy made the comment during a private conversation with Obama during a G20 summit in the French riviera town of Cannes last week and the remarks were overheard by a small number of journalists but not initially reported. "I cannot bear Netanyahu, he's a liar," Sarkozy told Obama during a frank exchange where the U.S. president took him to task for backing a Palestinian request for membership of the UN cultural heritage agency UNESCO. A Reuters reporter was among the journalists present and can confirm the veracity of the comments, which were relayed by a French internet outlet on Tuesday.
