It is tempting to say that we should end this pattern and raise standards everywhere. Perhaps we should extend habeas corpus globally, eliminate targeted killing and cease cooperating with intelligence services from countries that have poor human rights records. This sentiment, however, is unrealistic. The imperative to stop the terrorists is not going away. The government will find and exploit legal loopholes to ensure it can keep up our defenses.

This approach to detention policy reflects a sharp disjunction between the public's view of the terrorist threat and the government's. After nearly eight years without a follow-up attack, the public (or at least an influential sliver) is growing doubtful about the threat of terrorism and skeptical about using the lower-than-normal standards of wartime justice.

The government, however, sees the terrorist threat every day and is under enormous pressure to keep the country safe. When one of its approaches to terrorist incapacitation becomes too costly legally or politically, it shifts to others that raise fewer legal and political problems. This doesn't increase our safety or help the terrorists. But it does make us feel better about ourselves.
