the best defense is a good… lie

OK, so let me get this straight. We’re spending “$9 billion a year on a ‘missile defense’”: which a) doesn’t stop missiles even in simple testing and b) wouldn’t deter anyone from developing or deploying missiles. If that’s the case, I have a “bullet defense” here that consists of waving a pen vaguely in the direction of a loaded gun. How much is that worth? Do I get extra points if having the pen constitutes a treaty violation?
