Ignatius on Obama.

I don’t agree with the final conclusion, but the point is this: Even an Obama-supporting, center-left Washington Post writer, David Ignatius (Body of Lies), thinks that Obama has done our intelligence services damage with his decision to release the memos. It’s Amateur Hour at the White House. Again.

Obama seems to think he can have it both ways — authorizing an unprecedented disclosure of CIA operational methods and at the same time galvanizing a clandestine service whose best days, he told them Monday, are “yet to come.” Life doesn’t work that way — even for charismatic politicians. Disclosure of the torture memos may have been necessary, as part of an overdue campaign to change America’s image in the world. But nobody should pretend that the disclosures weren’t costly to CIA morale and effectiveness.

Put yourself in the shoes of the people who were asked to interrogate al-Qaeda prisoners in 2002. One former officer told me he declined the job, not because he thought the program was wrong but because he knew it would blow up. “We all knew the political wind would change eventually,” he recalled. Other officers who didn’t make that cynical but correct calculation are now “broken and bewildered,” says the former operative.

For a taste of what’s ahead, recall the chilling effects of past CIA scandals. In 1995, then-Director John Deutch ordered a “scrub” of the agency’s assets after revelations of past links to Guatemalan death squads. Officers were told they shouldn’t jettison sources who had provided truly valuable intelligence. But the practical message, recalls one former division chief, was: “Don’t deal with assets who could pose political risks.” A similar signal is being sent now, he warns.

One veteran counterterrorism operative says that agents in the field are already being more careful about using the legal findings that authorize covert action. An example is the so-called “risk of capture” interview that takes place in the first hour after a terrorism suspect is grabbed. This used to be the key window of opportunity, in which the subject was questioned aggressively and his cellphone contacts and “pocket litter” were exploited quickly.

Now, field officers are more careful. They want guidance from headquarters. They need legal advice. I’m told that in the case of an al-Qaeda suspect seized in Iraq several weeks ago, the CIA didn’t even try to interrogate him. The agency handed him over to the U.S. military.

Agency officials also worry about the effect on foreign intelligence services that share secrets with the United States in a process politely known as “liaison.” A former official who remains in close touch with key Arab allies such as Egypt and Jordan warns: “There is a growing concern that the risk is too high to do the things with America they’ve done in the past.”

If Obama means what he says about protecting the CIA workforce and its operational edge, he must give up the idea that he can please everyone on this issue. He should recommend limits on any congressional inquiry and resist demands for a special prosecutor. Instead, he should push the White House’s preferred alternative — a commission that can review secret evidence behind closed doors, then report to the nation.

America will be better off, in the long run, for Obama’s decision to expose the past practice of torture and ban its future use. But meanwhile, the country is fighting a war, and it needs to take care that the sunlight of exposure doesn’t blind its shadow warriors.
