Iran still has a nuclear program, Israel still wants to strike, and the U.S. still hopes to give diplomacy a chance—President Obama and Israeli Prime Minister Benjamin Netanyahu gave no indication of narrowing their differences after spending three hours conferring at the White House Monday. After the meeting, Netanyahu told reporters that the world is “united” over the threat in Iran. But U.S. officials said the two sides still differ on how to define the “red line” which Tehran must cross in order for a military strike to be considered. Officials have said they believe Iran is still a year away from being able to develop a nuclear weapon.
