【20世纪的战争与和平】阅读材料,回答问题

    20世纪所发生的战争显然从根上说是一种新形式的战争,即全面的战争。体现了工业化在军事行为方面产生的影响,第一次世界大战充分显示了全面战争的性质。战争越来越多地运用了更具破坏性的技术,战争组织不仅包括大规模的兵役征发,还包括政府通过强制规划和定量配给的方式对经济活动的控制,它还包括对媒体前所未有的控制,而且通过以煽动情绪为目的的强有力的宣传,激发起对国家事业的责任感,以及对敌人深深的非理性的仇视。全面战争的方式之一就是把军队和平民混淆起来,这种界限在先前的世界历史上常常限制了战争的破坏性。

    全面战争,像任何主要的历史发展一样,都有着混合性的结果,改善了的政府经济政策通常采取了新的保护工人的政策,对劳动大军的军事动员常常会导致妇女地位的重大突破。组建技术研究机构的强大努力经常会对经济领域产生侧面的影响,如合成橡胶和其它新材料的发明。即使如此,全面战争造成的灾难仍然是引人注目的。那种把一切可利用的资源都投入到军事行动中去的做法更能造成经济的崩溃。全面战争的结果之一是产生了一种胜利者在战争结束的谈判中更缺乏弹性的倾向;曾经艰苦奋战的人们觉得很难宽厚地对待他们的敌人,寻求报复经常会引发新的紧张,这种紧张很快直接导致新的冲突。战争引发的情绪和混乱局面也会导致国内新的暴力行动。
