What is the cause of realpolitik?

Realpolitik is driven by pragmatic considerations rather than ideological or ethical concerns, focusing on the practical realities of power and state interests. It arises from the need for leaders to navigate complex political landscapes, often prioritizing stability and national interests over moral or ideological commitments. This approach is influenced by historical contexts where power dynamics and immediate strategic needs overshadowed idealistic goals. Ultimately, realpolitik reflects a belief that effective governance requires a realistic assessment of human nature and political circumstances.
