**What does the term 'realpolitik' refer to in foreign affairs?**
Realpolitik is a pragmatic approach to foreign policy that prioritizes practical considerations over ideological or ethical concerns. It emphasizes the pursuit of national interests and the balance of power, often advocating for diplomacy and strategic alliances that may involve compromises or morally ambiguous actions. Governments employing realpolitik focus on achievable objectives and the realities of political situations rather than adhering strictly to principles or ideals. This approach can lead to effective, albeit controversial, foreign relations, as seen in historical contexts where leaders pursued relations with unsavory regimes for strategic benefits.
