Obama hosted his own Super Tuesday today, taking questions at his first press conference of the year. Though he started out cheering good economic data and unveiling a housing-relief plan for military members, the conversation kept going back to Israel and Iran at Q&A time. The president clarified that his declaration that America has Israel's back is a confirmation that the U.S. will continue to cooperate with Israel for its defense, like it does with other allies. However, he insisted, while the U.S. is committed to preventing Iran from acquiring a nuclear weapon, he still thinks this issue can be solved diplomatically, deriding presidential candidates who speak casually about war. "They don't have a lot of responsibilities. They're not commander in chief," he noted. "This is not a game, there's nothing casual about it."
