Bertrand Russell,
The Ethics of War
(1915)
“ So long as the principle of self-defence is recognized as affording always a sufficient justification for war, this tragic conflict of irresistible claims remains unavoidable. In certain cases, where there is a clash of differing civilizations, a war of self-defence may be justified on the same grounds as a war of principle. I think, however, that, even as a matter of practical politics, the principle of non-resistance contains an immense measure of wisdom if only men would have the courage to carry it out. ”
