I would move that, with the advent of techological advances at that times, and the general detachment that the domestic market generally had of international affairs at a time - a time of no TV and very slow moving news. That despite what was going on politically on the international stage - with the huge number of alliances and treaties being made in order to avoid a major war - the view of the man (and woman) in the street was one of detachment and feelings of peace - and a faith in the political system to avoid a war, at least on home soil and/or the home army. Remember you are not talking just about July 1914, but rather the years leading up to it.
My history books are stored away, but below is an interesting piece which partly explains the contradictory nature of this - the principle of 'you stop war, by preparing for it.'
International relations of the Great Powers (1814–1919)
Coming of World War
The main causes of World War I, which broke out unexpectedly in central Europe in summer 1914, included many factors, such as the conflicts and hostility of the four decades leading up to the war. Militarism, alliances, imperialism, and ethnic nationalism played major roles. However the immediate origins of the war lay in the decisions taken by statesmen and generals during the Crisis of 1914, which was sparked by the assassination of Archduke Franz Ferdinand (the Archduke of Austria Hungary) by a Serbian secret organization, the Black Hand.
By the 1870s or 1880s all the major powers were preparing for a large-scale war, although none expected one. Britain focused on building up its Royal Navy, already stronger than the next two navies combined. Germany, France, Austria, Italy and Russia, and some smaller countries, set up conscription systems whereby young men would serve from 1 to 3 years in the army, then spend the next 20 years or so in the reserves with annual summer training. Men from higher social statuses became officers.
