OF COURSE Iran has the capability!!!! It is a reasonably industrialized country with a technically savvy population and a strong higher education. But just like Japan, Germany, Brazil, Argentina and many other countries have the CAPABILITY to build weapons and yet never do, so Iran will be the same. Unless, of course, you attack it. Then all bets are off. And like it or not, If Iran really wanted to have nukes, they would have built them. Years ago.
