" Stopping a war; that is, stopping actual military combat, is not stopping a war in all its factors. During continuous hard strain a human mind can hold up; and it is truly amazing how much it can stand. Day by day, with that war-strain of worry pulling it down, it staunchly holds aloof, as a mighty oak in facing a storm. But it has a limit!! With too much too long strain, it will snap; just as that mighty oak will fall, in a long fight. "
