Q: Before 9/11, the CIA did not invest in developing a robust capability to conduct paramilitary operations with U.S. personnel. It relied on proxies instead, organized by CIA operatives without the requisite military training. The results were unsatisfactory. Whether the price is measured in either money or people, the United States cannot afford to build two separate capabilities for carrying out secret military operations, secretly operating standoff missiles, and secretly training foreign military or paramilitary forces. The United States should concentrate responsibility and necessary legal authorities in one entity. The post-9/11 Afghanistan precedent of using joint CIA-military teams for covert and clandestine operations was a good one. We believe this proposal to be consistent with it. Each agency would concentrate on its comparative advantages in building capabilities for joint missions. The operation itself would be planned in common. The CIA has a reputation for agility in operations. The military has a reputation for being methodical and cumbersome. We do not know if these stereotypes match current reality; they may also be one more symptom of the civil-military misunderstandings we described in chapter 4. It is a problem to be resolved in policy guidance and agency management, not in the creation of redundant, overlapping capabilities and authorities in such sensitive work. The CIA's experts should be integrated into the military's training, exercises, and planning. To quote a CIA official now serving in the field:"One fight, one team." Finally, to combat the secrecy and complexity we have described, the overall amounts of money being appropriated for national intelligence and to its component agencies should no longer be kept secret. Congress should pass a separate appropriations act for intelligence, defending the broad allocation of how these tens of billions of dollars have been assigned among the varieties of intelligence work. The specifics of the intelligence appropriation would remain classified, as they are today. <sep>What did the CIA rely on before 9/11 to work with US personnel?<sep>Military's training, exercises and planning
A:
No
