Sent 4: We had to live there."Sent 5: Zinni's distinct preference would have been to build up counterterrorism capabilities in neighboring countries such as Uzbekistan.
Sent 6: But he told us that he could not drum up much interest in or money for such a purpose from Washington, partly, he thought, because these countries had dictatorial governments.
Sent 7: After the decision-in which fear of collateral damage was an important factor- not to use cruise missiles against Kandahar in December 1998, Shelton and officers in the Pentagon developed plans for using an AC-130 gunship instead of cruise missile strikes.
Sent 8: Designed specifically for the special forces, the version of the AC-130 known as "Spooky"can fly in fast or from high altitude, undetected by radar; guided to its zone by extraordinarily complex electronics, it is capable of rapidly firing precision-guided 25, 40, and 105 mm projectiles.
Sent 9: Because this system could target more precisely than a salvo of cruise missiles, it had a much lower risk of causing collateral damage.
Sent 10: After giving Clarke a briefing and being encouraged to proceed, Shelton formally directed Zinni and General Peter Schoomaker, who headed the Special Operations Command, to develop plans for an AC-130 mission against Bin Laden's headquarters and infrastructure in Afghanistan.
Sent 11: The Joint Staff prepared a decision paper for deployment of the Special Operations aircraft.
Sent 12: Though Berger and Clarke continued to indicate interest in this option, the AC-130s were never deployed.
Sent 13: Clarke wrote at the time that Zinni opposed their use, and John Maher, the Joint Staff 's deputy director of operations, agreed that this was Zinni's position.
Sent 14: Zinni himself does not recall blocking the option.
Sent 15: He told us that he understood the Special Operations Command had never thought the intelligence good enough to justify actually moving AC-130s into position.
Sent 16: Schoomaker says, on the contrary, that he thought the AC-130 option feasible.
Sent 17: The most likely explanation for the two generals' differing recollections is that both of them thought serious preparation for any such operations would require a long-term redeployment of Special Operations forces to the Middle East or South Asia.
Sent 18: The AC-130s would need bases because the aircraft's unrefueled range was only a little over 2,000 miles.
Question: What option did Zinni deny blocking?.
Deployment of the AC-gunships.
