Which three sentences in this excerpt from franklin d. roosevelt's the "four freedoms" speech reflect his argument that victory in the war depends on the participation of all civilians? the happiness of future generations of americans may well depend upon how effective and how immediate we can make our aid felt. no one can tell the exact character of the emergency situations that we may be called upon to meet. the nation's hands must not be tied when the nation's life is in danger. we must all prepare to make the sacrifices that the emergency-almost as serious as war itself—demands. whatever stands in the way of speed and efficiency in defense preparations must give way to the national need. a free nation has the right to expect full cooperation from all groups. a free nation has the right to look to the leaders of business, of labor, and of agriculture to take the lead in stimulating effort, not among other groups but within their own groups. the best way of dealing with the few slackers or trouble makers in our midst is, first, to shame them by patriotic example, and, if that fails, to use the sovereignty of government to save government. as men do not live by bread alone, they do not fight by armaments alone. those who man our defenses, and those behind them who build our defenses, must have the stamina and the courage which come from unshakable belief in the manner of life which they are defending.
