War, n. A by-product of the arts of peace. The most menacing political condition is a period of international amity. […] “In time of peace prepare for war” has a deeper meaning than is commonly discerned; it means, not merely that all things earthly have an end – that change is the one immutable and eternal law – but that the soil of peace is thickly sown with seeds of war and singularly suited to their germination and growth. […] Let us have a little less of “hands across the sea,” and a little more of that elemental distrust that is the security of nations. War loves to come like a thief in the night; professions of eternal amity provide the night.
- Ambrose Bierce, The Devil’s Dictionary
