The author Barbara W. Tuchman discusses the perspective that war is an inherent part of human nature and societal evolution. A prominent figure argues that war embodies a biological necessity and reflects the natural law driving existence, where nations are compelled to either advance or face decline. This viewpoint suggests that stagnation is not an option for nations, particularly Germany, which must determine its path towards global dominance or face inevitable downfall.

This assertion implies that conflict is not merely a consequence of politics or human emotions but a fundamental aspect of survival and progress. The idea challenges the belief that peace can be a permanent state, highlighting that nations must engage in struggles to assert their influence and secure their future. Such a view reflects a deterministic outlook on history and human behavior, where the rhythm of war and peace is dictated by the imperative of existence itself.
