"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
