Nonsense.

What would Iran hope to gain by an attack on the US? Iran is smart enough to know that the American people are weary of war and know that stories of Iran's nuclear threat are no more real than the stories of Iraq's nuclear threat. All an attack would do is anger the American people against Iran and Iran knows better than to do that. So any attack that happens will be a false-flag attack, staged by the US or Israel to be blamed on Iran, similar to when Israel attacked the USS Liberty and initially tried to blame Egypt for it.

Fool me once...
