Imagine now that this report is NOT true, and considering all the usual "unnamed" sources, I won't be surprised if that is the case. All it will achieve is more anti-american resentment over yet another rumour, a big nothing. Somehow though, I think that anti-American sentiment is exactly what Seymour Hersch is after.
Iran is almost as bad as Iraq, I say a clean nuclear strike against the barbarian regime using what we know from Iraq to make the post war occupation much easier. Keep the military in place and declare martial law until democratic elections.
