As nebulous as it is , you can measure success by the declining number of terror attacks.

Really? I daily adorn a tin foil hat to protect against attacks from alien invaders. I also daily measure the success of this tactic by the declining number of alien attacks upon our planet. Therefore, the wearing of tin foil hats must be warranted, no?

LOL.. six.. that's not a very good analogy. We actually have a history of earthly terrorist attacks while we have had none from beyond.
Terrestrial attacks are verifiable and measurable.

But I get your point, to an extent.
That's sort of like vaccinations. If we don't get the flu or disease... did it work?
