Here is what I think the argument that often pops up that the allies were wanting and pushing for war....
The British non conscript Army needed almost 2 years from the outbreak of the war to get ready for proper offensive actions....
SURELY if Britain was expecting and hoping for a war, she would have introduced conscription in 1910 or thereabouts?
SURELY the French would have said... "well, we want a war, but are worried we will have to carry the first 2 years on our shoulders? We're not having any of it if Britain can't pull its weight?"
