I guess there's absolutely no reason for Iran to build a nuclear power plant other than to create nukes and shoot them off in missiles.
The other reason Iran is enriching uranium is produce medical nuclear isotopes.
Neocons can't stand the idea that since kicking the Shah out in 1979 and expelling their Israeli ambassador, they have become a regional technological powerhouse. It wasn't supposed to work like that. The idea that the country in the region that is most opposed to the US and Zionism is the country that's doing the best technologically must be killing Zionists and neocons.
I read a statistic where Iran is graduating as many engineers and the US is and they have about 1/4 the population.
If Iran's technical capability isn't stopped, then all is lost. This is why people want to attack Iran.
