Wars Are Not Won by Military Genius or Decisive Battles

War is the most complex, physically and morally demanding enterprise we undertake. No great art or music, no cathedral or temple or mosque, no intercontinental transport net or particle collider or space programme, no research for a cure for a mass-killing disease receives a fraction of the resources and effort we devote to making war. Or to recovery from war and preparations for future wars invested over years, even decades, of tentative peace. War is thus far more than a strung-together tale of key battles. Yet, traditional military history presented battles as fulcrum moments where empires rose or fell in a day, and most people still think that wars are won that way, in an hour or an afternoon of blood and bone. Or perhaps two or three. We must understand the deeper game, not look only to the scoring. That is hard to do because battles are so seductive.
