NSA Intercepts: Big Payoffs, Big Costs

Damn:

The surveillance files highlight a policy dilemma that has been aired only abstractly in public. There are discoveries of considerable intelligence value in the intercepted messages — and collateral harm to privacy on a scale that the Obama administration has not been willing to address.
Among the most valuable contents — which The Post will not describe in detail, to avoid interfering with ongoing operations — are fresh revelations about a secret overseas nuclear project, double-dealing by an ostensible ally, a military calamity that befell an unfriendly power, and the identities of aggressive intruders into U.S. computer networks.
