昭和天皇の運命『Hirohito (裕仁)』と 第33代米国大統領『ハリー・S・トルーマン』第二次世界大戦中の元指導者たち

#日本語 #ナレーションは実力派芸術家のパーカーアミン様 War is good for absolutely nothing. However much of the technology we depend upon today began as a kind of military technology. Wars put an enormous demand upon a nation's resources. Those resources include everything from materials to military personnel. It's expensive to wage war. And war places a burden upon a nation's citizens. As soldiers march off to battle, the people left behind must work even harder to keep the nation's infrastructure from collapsing. In general, wars tend to accelerate technological development to adapt tools for the purpose of solving specific military needs. Later, these military tools may evolve into non-military devices.
