How did Nixons idea of realpollitik differ from the idea of containment?

Nixon's idea of realpolitik emphasized pragmatic and strategic diplomacy over ideological considerations, focusing on national interests and power dynamics rather than the rigid containment of communism. In contrast, the containment policy aimed to prevent the spread of communism globally through a more confrontational and ideological approach. While containment sought to oppose and isolate communist states, realpolitik encouraged engagement with all nations, including those with differing ideologies, to achieve stability and balance of power. This shift allowed for more flexible foreign policy decisions, particularly with key players like China and the Soviet Union.
