1. "We don't say yes or no to Israeli military operations. Israel is its own sovereign. We are in close contact with Israel and we talk about the diplomatic track we're on... They've said diplomacy can work here, and I know they're doing their part to talk with all countries with which they have diplomatic relations to explain why it is important to have a tough edge to our diplomacy." Those were the words of Secretary of State Condoleezza Rice on August 7th, and it was reasonable to take them as a green light to those in Israel who advocate for an Israeli attack on Iran's nuclear installations. They came in the lingering and sour aftermath of widespread reports that the United States had effectively vetoed any unilateral Israeli action, and diverse signs that the US itself was moving to a more nuanced Iran policy. In particular, Prime Minister Olmert had written a letter of alarm to President Bush towards the end of July, a letter protesting the American rapprochement with Iran and expressing Israel's profound anxiety at the imminent existential threat of Iran's nuclear ambitions.
So the Rice statement could be seen as reassurance. If Israel was so disposed, America would not intervene to stop it.
