Hersh is an a-hole; take his reports at your own risk...he railed and railed and railed at the end of the Bush presidency that he (hersh) had sensitive intelligence stating GWB was going to invade iran during the last six months of his presidency...
I don't consider him to be a reliable source. Just entertainment.
I don't consider the FBI a reliable or honest source either.
You think there is no plan on an invasion of Iran today?
