Rudolf Hess (in Baird, J. W., 1990): "The stream of blood which for Germany is eternal — the sacrifice of German men for their Volk is eternal — therefore Germany will also be eternal."

General Douglas MacArthur's Farewell Speech of May 12,1962: "Only the dead have seen the end of war." 

There is no "purpose" to war: except to produce an endless stream of blood: testifying to the "eternity" of one's nation.
