Iran missle threat

President Bush faces difficult choices as Iran moves forward with its uranium enrichment and missle development.

The shahab-6 missle currently has a range of 5,470-5,500 and 5,632-6,200 kilometers with a 1,000-750-500 kilogram warhead.

This is enough to hit London and Paris, if further upgraded it could strike the continental United States. This missle is based on a combination of North Korea and old Soviet technology subsequently enhanced by the Iranians.

Using att I have found than by late 2008 the People's Islamic Republic of Iran will have intercontinental ballistic missles with the operation capability of delivering nuclear warheads to the continental United States.
