Here's what President Bush said about why the Iranians are Islamic extremists in a speech on September 5, 2006:
Like al Qaeda and the Sunni extremists, the Iranian regime has clear aims: They want to drive America out of the region, to destroy Israel, and to dominate the broader Middle East. To achieve these aims, they are funding and arming terrorist groups like Hezbollah, which allow them to attack Israel and America by proxy. Hezbollah, the source of the current instability in Lebanon, has killed more Americans than any terrorist organization except al Qaeda. Unlike al Qaeda, they've not yet attacked the American homeland. Yet they're directly responsible for the murder of hundreds of Americans abroad. It was Hezbollah that was behind the 1983 bombing of the U.S. Marine barracks in Beirut that killed 241 Americans. And Saudi Hezbollah was behind the 1996 bombing of Khobar Towers in Saudi Arabia that killed 19 Americans, an attack conducted by terrorists who we believe were working with Iranian officials. Just as we must take the words of the Sunni extremists seriously, we must take the words of the Shia extremists seriously. Listen to the words of Hezbollah's leader, the terrorist Nasrallah, who has declared his hatred of America. He says, "Let the entire world hear me. Our hostility to the Great Satan [America] is absolute… Regardless of how the world has changed after 11 September, Death to America will remain our reverberating and powerful slogan: Death to America." Iran's leaders, who back Hezbollah, have also declared their absolute hostility to America. Last October, Iran's President declared in a speech that some people ask — in his words — "whether a world without the United States and Zionism can be achieved… I say that this… goal is achievable." Less than three months ago, Iran's President declared to America and other Western powers: "open your eyes and see the fate of pharaoh… if you do not abandon the path of falsehood… your doomed destiny will be annihilation." Less than two months ago, he warned: "The anger of Muslims may reach an explosion point soon. If such a day comes… [America and the West] should know that the waves of the blast will not remain within the boundaries of our region." He also delivered this message to the American people: "If you would like to have good relations with the Iranian nation in the future… bow down before the greatness of the Iranian nation and surrender. If you don't accept [to do this], the Iranian nation will… force you to surrender and bow down."
Here is what the President said in the same speech about negotiating with Islamic extremists (stated in the context of the Sunni extremists the President later said the Iranians were just like):
The goal of these Sunni extremists is to remake the entire Muslim world in their radical image. In pursuit of their imperial aims, these extremists say there can be no compromise or dialogue with those they call "infidels" — a category that includes America, the world's free nations, Jews, and all Muslims who reject their extreme vision of Islam. They reject the possibility of peaceful coexistence with the free world. Again, hear the words of Osama bin Laden earlier this year: "Death is better than living on this Earth with the unbelievers among us." These radicals have declared their uncompromising hostility to freedom. It is foolish to think that you can negotiate with them. (Applause.)
Question: Other than the fact that we have now caught the Iranians red-handed killing Americans in Iraq and that the Iranians have made plain that they have no intention of foregoing their nuclear ambitions, what has changed in the last six months to suddenly transform these uncompromising, murdering extremists into negotiation material?
