In his book "Types of Courage", US President John F. Kennedy reveals to us the concept of "political courage", not merely as a heroic stance, but rather as a difficult moral choice that embodies a commitment to principles and the sacrifice of personal interests for the public good. In his book, Kennedy reviews inspiring examples of eight members of the US Senate who showed exceptional courage in the face of pressure and threats, defending their principles and sacrificing their political path in order to achieve what they believe in. In this book, Kennedy presents a deep vision of moral political leadership, stressing the importance of courage, integrity, and sacrifice as essential qualities for any politician who seeks to serve his people and build a better society.
