In war, #hashtags are no substitute for victory

From Williamson and Millett's A War to Be Won:

Moral righteousness alone does not win battles. Evil causes do not necessarily carry the seeds of their own destruction. Once engaged, even just wars have to be won-- or lost-- on the battlefield.

John Keegan, Intelligence in War:

A wise opinion would be that intelligence, while necessary, is not a sufficient means to victory. Decision in war is always the result of a fight, and in combat willpower always counts for more than foreknowledge.
