I call upon the scientific community in our country, those who gave us nuclear weapons, to turn their great talents now to the cause of mankind and world peace: to give us the means of rendering these nuclear weapons impotent and obsolete.
Ronald ReaganOur status as a free society and world power is not based on brute strength. When we've taken up arms, it has been for the defense of freedom for ourselves and for other peaceful nations who needed our help. But now, faced with the development of weapons with immense destructive power, we've no choice but to maintain ready defense forces that are second to none. Yes, the cost is high, but the price of neglect would be infinitely higher.
