To begin with, the perpetrators of a successful double-agent operation against al Qaeda in the Arabian Peninsula would not want to brag about their coup for years. Presumably, al Qaeda in the Arabian Peninsula will now use the press reports to walk the dog back to determine whose misplaced trust allowed the agent to penetrate it. That will make the next operation more difficult. Other intelligence operations — and we can assume they are up and running — may also become compromised as the press reports give al Qaeda in the Arabian Peninsula new clues.

Likewise, the next time the CIA or foreign intelligence agency tries to recruit a double agent, the candidate will judge his handlers wretched secret keepers, regard the assignment a death mission and seek employment elsewhere.

Last, the leaks of information — including those from the lips of Brennan, Clarke and King — signal to potential allies that America can’t be trusted with secrets. “Leaks related to national security can put people at risk,” as Obama put it today in a news conference.

The ultimate audience for the leaks investigation may not be domestic but foreign. Obviously, the government wants to root out the secretspillers. But a country can’t expect foreign intelligence agencies to cooperate if it blows cover of such an operation. I’d wager that the investigations have only begun.
