It's still not a trivial exercise to build an atomic bomb. It's a mistake to believe that it is. While it's true that the Hiroshima uranium bomb was never tested before hand and the Trinity test, the first atomic explosion was a test of the Nagasaki bomb, a completely utterly different design that used plutonium not uranium, the work that went into the theory, design and fabrication of the Hiroshima bomb and the others, was massive. It took $4 billion dollars in 1945 money. About 2 billion to build the nuclear materials separation facilities at Oak Ridge, Hanford and other places. And about $2 billion to build the Los Alamos facility, staff it and run it and build Bombs 1, 2 and 3. Now let's say for the sake of argument that today the methods are 10x more efficient. That still leaves a massive debt and and even more massive pile of nuclear waste. I would expect that a crash program like Iran's - even though it's slow moving, will eventually generate incalculable environmental damage as well as significant long term diseases and deaths from nuclear materials and related chemical toxicity.
