That's what I was wondering. Even if the triggers could deteriorate, could they be used as dirty nukes with enough dynomite or fertilizer? Not nearly as scary. But also, the possibility of a trigger expert being hired, that would keep a commander-in-chief up at nights.
No matter what, I believe one thing: we must defeat this evil, the sooner the better. Or they will destroy us. Worse case scenario: maybe we only catch half of these clowns and only lose half of our cities.
