The Battle Of The Potomac

"But to carry the analogy further, it was not passive defenses but the destruction of the U-Boat lairs and its transit routes which finally ended the Nazi threat. The U-Boats were "intercepted" in transit, such as in the Bay of Biscay. And finally the U-Boat pens themselves were taken and the Nazi naval threat was ended forever. This is what must happen to IED threats like the explosively formed projectiles and their associated targeting systems. You can't keep bailing the water. You have to turn off the faucet.

If Iran insists upon sending U-Boats -- pardon, explosively formed projectiles -- to attack Americans, it is effectively opening hostilities on the US. That politicians in Washington choose not to regard it as such is not really Teheran's fault. One can accuse the Ayatollahs of many things, but creating American indecision cannot be blamed on them. That is the result of politics along the Potomac."

UPDATE: "We should also note that being able to intercept and decrypt their communications was critical to countering the U-boat threat."
