Obama Says Iranian Nuclear Weapon is a "Red Line"

Says such a development would be a threat to American interests

On the eve of his first visit to Israel as U.S. president, Barack Obama told an Israeli television network that "Iran possessing a nuclear weapon is a red line" for his administration.

In an interview with Channel 2 news broadcast on Thursday night, Obama said he will tell Prime Minister Benjamin Netanyahu, who he is due to meet in Jerusalem next week, that if diplomatic efforts to thwart the Iranian nuclear program fail, he is ready to use other means prevent the Islamic Republic from obtaining a nuclear bomb.
