It reflects a context of global conflict during a time when many nations, especially in Europe, were deeply embroiled in war. The opening of the book includes a foreword from Maxim, where he expresses concern about America's readiness to face potential invasions. He critiques the pacifist movement, suggesting that its ideas are misguided and detrimental to national security.
