In an interview with Channel 2 on Friday, Peres said that he believes Israel is closer to utilizing the military option in dealing with Iran's nuclear program than it is to finding a diplomatic solution to the threat.The president suggested that the media speculation about a potential attack on Iran may have some basis in truth. "Intelligence services in many countries are looking at the clock and warning their leaders that not much time remains. I do not know if these world leaders will act on this advice." Peres said that Iran could be as close as six months from becoming nuclear-armed and it is Israel's role to warn the world of the danger. He suggested that the speculation about an attack on Iran may be a way of reminding the world of the Iranian threat.
