The reality is that all of these things – and more – are changes of degree. They are changes of mode in the manner of prosecution of war. But they are not changes to the substance of warfare. The nature of war has not changed since man fought as bands of hunter-gatherers on the African savannah. It is still – primarily and fundamentally – a deeply psychological phenomenon. It is still a contest between evolved human brains.
The same dynamics of advance, retreat, feint, ruse, confidence and fear decide the outcomes of battles, and of wars. The physicality of war - the bombs, bullets and bayonets - are merely there to affect your enemy's state of mind, as was illustrated so clearly two weeks ago
when Ukraine’s recapture of Russian-occupied territory prompted many frightened Russian soldiers to surrender or flee their positions.
This fundamental psychological truth about warfare tells us some other things as well. It tells us that strategy – how you change your enemy’s psychology and make them do what you want – is supreme. It also tells us that logistics – your resources or tools for the job – are of crucial importance. And it tells us that morale – that ancient intangible of camaraderie and esprit de corps – is a battle winner.
The side that has these three things right – strategy, logistics and morale – will win the war. And this was as true in the Neolithic Period as it is in the new millennium.
