It takes 1500 centrifuges working 1 year continuosly to make 60 kg of U235. Iran says it has 50000 centrifuges so :- 1500:365 :: 50000: X X= 1500/50000 *365 = 11 days . If you add 5 woorking days to encase the U235 and make a 'dirt' tactical Nuclear bomb. Ths could be Transported by their Shahab 3 missile having a range of 2000 KM. They can in effect hit Israel on 25 April 2007. This would provoke an immediate annihilatory resonse by Israeli, totally nuking Iran and to an extent neighbouring Pakistan. Pak will strike a comprehensive nuclear attack against Israel, forcing America to retaliate. Pakistan will hit India , causing Russia to get in the conflict. And all out world war 3 with total destruction of the world by te end of next month. How does that look... We all are going to die by next month. I didn't even had sex till now.And so has so many of us. I have a plan but. You give me 5000 Billion dollars and 50000 US and European troops to dispose and I can prevent WW 3.
