Make Business, Not War?

"...The outbreak of the First World War in 1914 signaled the end of an era for capitalism. Until then, despite constant threats of revolt by the poor and economic problems, the only way for capitalism had seemed to be up - and outwards.

     This view was rudely shaken by the First World War, which totally discredited the then popular view that the thickening web of commerce, which capitalism was building across the globe, would make wars between nations thus intertwined highly unlikely, if not totally impossible."
