"By calling attention to 'a well regulated militia,' 'the security of the nation,' and the right of each citizen ‘to keep and bear arms,' our founding fathers recognized the essentially civilian nature of our economy... The Second Amendment still remains an important declaration of our basic civilian-military relationships in which every citizen must be ready to participate in the defense of his country. For that reason I believe the Second Amendment will always be important." - John F. Kennedy

"They tell us that we are weak - unable to cope with so formidable an adversary. But when shall we be stronger? Will it be when we are totally disarmed, and when a British guard shall be stationed in every house? Three million people, armed in the holy cause of liberty, are invincible by any force which our enemy can send against us." - Patrick Henry
