Everybody's Talkin'

Item: Obama is talking about nuclear disarmament.

Consider the supreme achievement of the human race. We now have the capacity to destroy all life on the planet, if we choose to do so.

Isn't it great? In the middle ages the closest thing to a superweapon they had was something called Greek fire. To this day nobody knows exactly how it was made (it was a military secret), but pine resin and sulfur were certainly two main ingredients. They'd set this stuff on fire and throw it with catapults, and it was a terrible weapon indeed.

But blow up the world? They couldn't get close to doing that back then. They weren't as advanced as we are.
