What is the cause of realpolitik?

Realpolitik is a political theory and practice that focuses on the practicalities of politics, rather than on moral or ethical considerations. It is based on the idea that the only way to achieve political goals is to be realistic about the world as it is, and to use whatever means necessary to achieve those goals.

The cause of realpolitik is the fact that the world is a complex and often dangerous place. In order to survive and prosper, states must be willing to do whatever it takes to protect their interests. This can include using force, deception, or other means that may not be considered moral or ethical.

Realpolitik is often contrasted with idealism, which is a political theory that focuses on the importance of moral and ethical considerations in politics. Idealists believe that the best way to achieve political goals is to be principled and to stick to one's values, even if it means sacrificing short-term gains.

Realists, on the other hand, believe that it is more important to be practical and to adapt to the changing circumstances of the world. They argue that it is impossible to always be moral or ethical in politics, and that it is sometimes necessary to make difficult choices in order to achieve the greater good.

The debate between realpolitik and idealism has been going on for centuries, and there is no easy answer to which one is right. Ultimately, the best approach to politics is likely a combination of both realism and idealism. It is important to be both principled and practical, and to be willing to adapt to the changing circumstances of the world.
