Input: Even after Bin Laden's departure from the area, CIA officers hoped he might return, seeing the camp as a magnet that could draw him for as long as it was still set up. The military maintained readiness for another strike opportunity. On March 7, 1999, Clarke called a UAE official to express his concerns about possible associations between Emirati officials and Bin Laden. Clarke later wrote in a memorandum of this conversation that the call had been approved at an interagency meeting and cleared with the CIA. When the former Bin Laden unit chief found out about Clarke's call, he questioned CIA officials, who denied having given such a clearance. Imagery confirmed that less than a week after Clarke's phone call the camp was hurriedly dismantled, and the site was deserted. CIA officers, including Deputy Director for Operations Pavitt, were irate." Mike" thought the dismantling of the camp erased a possible site for targeting Bin Laden. The United Arab Emirates was becoming both a valued counterterrorism ally of the United States and a persistent counterterrorism problem. From 1999 through early 2001, the United States, and President Clinton personally, pressed the UAE, one of the Taliban's only travel and financial outlets to the outside world, to break off its ties and enforce sanctions, especially those relating to flights to and from Afghanistan. These efforts achieved little before 9/11. In July 1999, UAE Minister of State for Foreign Affairs Hamdan bin Zayid threatened to break relations with the Taliban over Bin Laden. The Taliban did not take him seriously, however. Bin Zayid later told an American diplomat that the UAE valued its relations with the Taliban because the Afghan radicals offered a counterbalance to "Iranian dangers" in the region, but he also noted that the UAE did not want to upset the United States.

Does the response "March 7, 1999" correctly answer the question "When and why did the UAE Minister of State for Foreign Affairs Hamdan bin Zayid threaten to break relations with the Taliban over Bin Laden?"?

The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exceptionthe presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced societythe ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d.

At the conference room table was White House Deputy Chief of Staff Joshua Bolten. Bolten watched the exchanges and, after what he called "a quiet moment,"suggested that the Vice President get in touch with the President and confirm the engage order. Bolten told us he wanted to make sure the President was told that the Vice President had executed the order. He said he had not heard any prior discussion on the subject with the President. The Vice President was logged calling the President at 10:18 for a twominute conversation that obtained the confirmation. On Air Force One, the President's press secretary was taking notes; Ari Fleischer recorded that at 10:20, the President told him that he had authorized a shootdown of aircraft if necessary. Minutes went by and word arrived of an aircraft down in Pennsylvania. Those in the shelter wondered if the aircraft had been shot down pursuant to this authorization. At approximately 10:30, the shelter started receiving reports of another hijacked plane, this time only 5 to 10 miles out. Believing they had only a minute or two, the Vice President again communicated the authorization to "engage or "take out" the aircraft. At 10:33, Hadley told the air threat conference call: "I need to get word to Dick Myers that our reports are there's an inbound aircraft flying low 5 miles out. The Vice President's guidance was we need to take them out." Once again, there was no immediate information about the fate of the inbound aircraft. In the apt description of one witness, "It drops below the radar screen and it's just continually hovering in your imagination; you don't know where it is or what happens to it." Eventually, the shelter received word that the alleged hijacker 5 miles away had been a medevac helicopter. Transmission of the Authorization from the White House to the Pilots The NMCC learned of United 93's hijacking at about 10:03. At this time the FAA had no contact with the military at the level of national command. The NMCC learned about United 93 from the White House.
