The relationships involving BCCI, the CIA, and members of the United States and foreign intelligence communities have been among the most perplexing aspects of understanding the rise and fall of BCCI. The CIA’s and BCCI’s mutual environments of secrecy have been one obvious obstacle. For many months, the CIA resisted providing information to the Subcommittee about its involvement with and knowledge of BCCI. Moreover, key players who might explain these relationships are unavailable. Some, including former CIA director William Casey, and BCCI customers and Iranian arms dealers Ben Banerjee and Cyrus Hashemi, are dead. Others, including most of BCCI’s key insiders, remain held incommunicado in Abu Dhabi.
