For Germany in the late 30's, war was a certain thing, basically due to the ending of the Great War, which had pointed at Germany as sole innisiator of that conflict in the Treaty of Versailles and punished Germany severely as a result. This alone was more than enough reason for the German people and not only the politicians to set things back to more accaptable standards (in a German point of view), meaning the recapture of lost territories and the punishing of the "Evil" Entente powers of the Great War, as well as the equally evil Communist USSR, which was seen as a serious threat to the world.
Rubbish. The German people knew quite well what had happened in 1914-1918. They had marched off to war with the Kaiser and his generals telling them victory was certain and would be quick.
But there was no quick victory, only gigantic slaughters that killed over 2M German soldiers. The German army reached the outskirts of Paris, and knocked out Russia. But even then victory was impossible.
By 1918 the people were starving, and the army collapsed under overwhelming Allied attack - as did all of Germany's allies. (The
dolchstosslegende was a stick to beat the Social Democrats.)
The war was a colossal disaster for Germany.
Hardly anyone in Germany wanted to try it again. The professionals of the General Staff looked at the national resources and geopolitical situation, and couldn't see any way to do better a second time. The Social Democrats and Communists were opposed to war on principle. The business elite would have to pay for a war. And most people were afraid that aerial bombing would destroy
everything. (The original expectations for aerial bombing were greatly exaggerated; British civil defense authorities estimated more air-raid casualties for the first week of hostilities than Britain actually suffered in the entire war.)
Without Hitler to drag them into, the German people would never have started a war.
Germany suffered more war dead, proportionately, than Britain. And Britain was so traumatized that its intelligentsia became largely pacifist. ("This House will not fight for King and Country.")
