Pregnant With War

What did Keegan mean when he said, "For the truth of twentieth-century European civilization was that the world it dominated was pregnant with war."?

          To start, by this sentence, Keegan implies that they were prepared for such a war.  With a full scale industrial revolution, vast population increase resulting in large armies, a war was becoming increasingly inevitable.  There were increasing medical and dietary advantages which made men more fit to go and fight in the military.  Also Keegan tells us that "The enormous enlargement of European economies was meanwhile creating the tax base by which new armies of conscripted recruits were supported" (Keegan 15). This means that nations became more advanced in gathering taxes and being aware of their population so that men could be recruited for the army and paid for it.  Countries started conscription and became more obsessed with the idea of war, even to the extent that they were using a majority of revenue to buy military weapons.  The idea of war was all-powerful.  Event the The nature of being a soldier changed dramatically into a willing and devoted persona.  The 19th century reinforced the idea of nationalism and die-hard patriotic ideals that citizens of every nation became stuck to.  By his mention of being "pregnant with war", Keegan is attempting to manifest the concept that all of the previous factors led to a world where every country had war on their minds and the means to prepare for even the slightest conflict to emerge and bring out war.
