The truth is that because the P5+1 are likely to try and conclude an agreement by the end of this month, Prime Minister Netanyahu has to get his points across right now. And when you are talking about the destiny of Israel, the future security of Israel, when you are the prime minister of Israel you have to make certain that Iran doesn't get nuclear weapons. And you have to be really certain, not "perhaps," or "we'll see." When the Iranians are in the phase of uranium enrichment, a lot of people know what they're doing. They have visits of the International Atomic Energy Agency. But when they're actually assembling the weapon, many people including former U.S. Secretary of Defense Robert Gates said there's a real problem when they are on the verge because you may not know when they cross over and obtain a weapon.
