When President Obama sits down face-to-face with Israeli Prime Minister Benjamin Netanyahu next week to discuss Iran, he will be staring down the greatest challenge on Israel he’s faced during his presidency.
It is the first time Obama has met Netanyahu since last spring, when the Israeli leader appeared to lecture the president on his country’s history in front of cameras at the White House.
Whatever tensions exist could be exacerbated by the looming crisis that provides a backdrop for the election-year meeting.
Israel believes time is running out for a military strike against Iran that would prevent the Islamic republic from developing nuclear weapons, something Israel sees as an existential threat.
