I fully agree with you over "why we need a bomb"? but I disagree that we already have it! Its not as simplistic. We have the ability to develop as we have the scientific know-how for both uranium and thorium based reactions, but that does not imply we have the capability. Its debatable whether we need to focus on bomb development or not, or do we want to buy bombs and sacrifice bomb development rights for energy needs. That's the real dialemma.
