It stands to reason you've got to have a war. Not because anybody wants it, of course, but because there's an army. An army here and an army there and armies all over the shop. Armies is for wars and wars is for armies. That's only plain common sense.
In this quote by Anthony Burgess, he suggests that the existence of armies inevitably leads to the occurrence of wars. It emphasizes a logical connection between the presence of military forces and the likelihood of conflict, highlighting that wars are a consequence of having organized armies. While the sentiment is not that people desire war, the mere existence of armed forces creates an environment where war becomes almost unavoidable.
This perspective reflects a pragmatic view on warfare, where the structure and readiness of military power prompt actions that align with their purpose: to engage in battle. Burgess’s statement underscores how societal and institutional factors, such as the accumulation of military resources, can drive nations towards conflict despite the absence of a collective desire for war.
