James Madison,
The Federalist
(1863, Dawson edition)
“ How could a readiness for war in time of peace be safely prohibited, unless we could prohibit, in like manner, the preparations and establishments of every hostile nation? The means of security can only be regulated by the means and the danger of attack. They will in fact be ever determined by these rules, and by no others. It is in vain to oppose Constitutional barriers to the impulse of self-preservation. It is worse than in vain; because it plants in the Constitution itself necessary usurpations of power, every precedent of which is a germ of unnecessary and multiplied repetitions. ”
