The United States of America has been at war for almost all of its 250 years of existence. From the wars of independence to current armed conflicts, its armed forces have not only shaped American identity, but also influenced the political decisions of its leaders. The documentary delves deep into this complex history and analyzes the hot and cold wars that shaped the development of the USA, along with lessons for the future.

Do military decisions today shape the world of tomorrow and what are the effects on democracy and society? And as the US president begins his new term in office, the question also arises: what role does the army play in Donald Trump's understanding of the world?
