Many aff’s making security claims on the last two topics have responded to K’s with an argument along the lines of: we can’t ignore the worst case scenarios, to do so would cause disaster. Cards I would lump into this broad category are like that Macy SFP is backwards card, Fitzsimmons, most of the fear good cards like Sandman, a bunch of Krauthammer cards about terror/attacks on the US etc.
Most negatives respond to this by reading the monkeys throwing darts card, and maybe a Bleiker card about how prediction hurts agency with no impact. I don’t really think these cards are adequate.
