   20世纪的和平与战争

    材料一    对朝鲜的攻击已无可怀疑地说明，共产主义已不限于使用颠覆手段来征服独立国家，现在要使用武装的侵犯与战争。它违抗了联合国安理会为了保持国际和平与安全而发出的命令。在这种情况下，共产党部队的占领福摩萨，将直接威胁太平洋地区的安全，及在该地区执行合法与必要职务的美国部队。

据此，我已命令第七舰队阻止对福摩萨的任何攻击。作为这一行动的应有结果，我还要求福摩萨的中国政府停止对大陆的一切海空行动。第七舰队将监督此事的实行。福摩萨未来地位的决定，必须等待太平洋安全的恢复、对日本的和平解决、或联合国的审议。

    材料二    在今天的情况下，共产党俄国和它的盟国中国在政治体制上对东南亚施加的影响，不管它们采取的是哪一种手段，对整个自由世界来说都将是一种严重的威胁。美国认为不能消极地来承认这种可能性，而是应该采取联合行动来对付它。这样做或许要冒严重的风险。然而，假如我们今天不敢下定决心去解决的话，那么几年以后我们将面临更加严重的危机。──《美国国务院公报》（1954年1月25日）
