In Seymour Hersh's much-discussed new article on President Bush and Iranian regime-change there's this graf (emphasis added)...

There is a growing conviction among members of the United States military, and in the international community, that President Bush's ultimate goal in the nuclear confrontation with Iran is regime change. Iran's President, Mahmoud Ahmadinejad, has challenged the reality of the Holocaust and said that Israel must be "wiped off the map." Bush and others in the White House view him as a potential Adolf Hitler, a former senior intelligence official said. "That's the name they're using. They say, 'Will Iran get a strategic weapon and threaten another world war?'"

This claim is certainly ambiguously sourced. But if true, it suggests that our nation's fate is again in the grip of George W. Bush's grandiosity. And if so, no eventuality is too far-fetched. Nothing can be ruled out.
