The iron curtain divided the world into what?

The Iron Curtain divided the world into two opposing spheres: the Western bloc, led by the United States and its NATO allies, which promoted democratic governance and capitalism, and the Eastern bloc, led by the Soviet Union and its satellite states, which embraced communism and authoritarian rule. This division symbolized the ideological conflict of the Cold War, highlighting the stark differences in political systems and economic structures. The Iron Curtain also represented the physical and political boundaries that separated Europe during this period.
