Iran's Christmas present

I do not know if you people are into modern problems, but heres an interesting one: Israel claims that if Iran doesnt Disarm their nuclear weapons, they will strike Iran before christmas. This is all well and good, but whats the proof of this? Well first, i just recently heard that the Ayatolla of Iran (religiuos leader of Iran) has been hidden in the mountains (to protect from a possible attack?) and Iran has begun enriching more Uranium (main material used for nuclear weapons). Also, Russia has claimed that if Israel attacks Iran, Russia may join in on the fight (may be leading to world war III). Thoughts?
