阅读下列材料，回答问题：

材料一：各缔约国：为促进国际合作，保证国际的和平与安全，承担不从事战争之义务，维护各国间基于正义与荣誉之公开邦交，严守国际法之规定，已为今后各国政府行为之规范。

——《国际联盟盟约》

材料二：建立一个世界上所有国家都参加的联盟（国联），不管是大国还是小国，一起合作来维护和平，这是威尔逊总统梦寐以求的事……联盟，从来就没有取得他的创始人所期望达到的出色成就……在所有重大危机中，人们不是不听联盟的话，就是根本不理睬它。

材料三：“一、维护国际和平与安全，并为此目的：采取有效集体办法，以防止且消除对手和平之威胁，直至侵略行为或其他和平之破坏，并以和平且依正义及国际法之原则，调整或解决足以破坏和平之国际争端或情势……”此为联合国之宗旨。

材料四：联合国成立以来三十年的成就尚可予人深刻印象……但它在普遍栽减军备方面却一事无成。它也未能制止苏美之间日益增长的摩擦，而这种摩擦肯定是对国家和平的威胁……然而，可以论断，联合国因主要由于提供权宜的办法和讨论各种牢骚的讲坛，有助于防止两个巨人迎面冲突。结果，种种危机愈演愈烈，成为剧烈的争吵，但未形成毁灭世界的大规模祸殃。

——材料二、三、四均选自伯恩斯·拉夫尔《世界文明史》
