In an interview with the Atlantic's Jeffrey Goldberg, the new Israeli Prime Minister challenges Barack Obama to prevent Iran from acquiring nuclear weapons - an event Israeli intelligence believes is imminent. If Obama fails, Israel might attack. Within months. Not a big policy change here, but the apocalyptic tone of Netanyahu's rhetoric, on the eve of the G20, suggests to me that the new Israeli government wants to rattle the cage a bit.
