Aimed at conspiracy theorists. If America does have a super weapon that is helping to keep us alive?

dont you think people should stop looking for it so "expose the truth" Look what happened witht the nuclear bombs. America used to be the only country with them then "the truth was exposed" and now we are closer to ending the world than ever. My personal opinion is that if we have a magical weapon that scares the hell out of the enemy leaders dont go looking for it. Id rather be ignorant and safe rather than toss another possible doomsday weapon unto the world scene.
