Iran Q and A

A good article from McClatchy in question and answer format on Iran's nuclear power/weapons interests:

Some common questions about Iran's nuclear program

Q. Is Iran trying to develop nuclear weapons?

A. It says its nuclear research is for energy purposes, which is permitted under the 1968 nuclear Non-Proliferation Treaty. But the Bush administration and some Western European governments charge that Iran is using a civilian energy program as a cover to build a nuclear weapon. They cite Iran's already ample energy resources in oil and natural gas, its failure to declare its uranium-enrichment program until an opposition group revealed it and other experiments it's conducted that point to an interest in weapons.

There is a significant difference between enriching uranium for power versus enriching it for weapons. The latter is significantly trickier to do than the former.
