Found doodle. I picked it off the floor from an Asteroid Deflection Conference I attended in DC. I was only allowed to attend the open half of the conference. For the half where they discussed the use of nuclear weaponry, you needed clearance.
Any time the guys with clearance had reason to refer to nuclear weaponry, they referred to it as "tried-and-tested 1950s technology." I've got to presume that today's weaponry is even scarier.
