The first rule about Poodle Blanket is that you don't ask about Poodle Blanket

Awesome: Our secret plans for how to handle a confrontation with the Soviet Union over West Berlin were called "Poodle Blanket". Less-than-awesome: Despite the fact that Berlin is now united and the Soviet Union no longer exists, the Department of Defense continues to insist on keeping the details of Poodle Blanket under wraps. The National Security Archive at George Washington University—which made the first FOIA request for Poodle Blanket (just can't say that enough) documents back in 1992—has an interesting post asking why Poodle Blanket (Poodle Blanket, Poodle Blanket, Poodle Blanket!) is still classified material.
