You see, when a nation threatens another nation the people of the latter forget their factionalism, their local antagonisms, their political differences, their suspicions of each other, their religious hostilities, and band together as one unit. Leaders know that, and that is why so many of them whip up wars during periods of national crisis, or when the people become discontented and angry. This is the explanation of all wars, all racial and religious hatreds, all massacres, and all attempts at genocide.
