What best characterizes the international order after 1945?

• A. Bipolar world
• B. Unipolar world
• C. Anarchic isolation
• D. Global empire

Answer: (A)

Two great powers dominated the international system in the decades after World War II. The United States and the Soviet Union forged opposing blocs, each pulling in allies and shaping global politics through military pacts, economic aid, and ideological competition. NATO and Western alliances anchored the U.S. side, while the Warsaw Pact and Soviet-aligned states formed the Eastern Bloc. The presence of armaments races, ideological conflict, and proxy wars in multiple regions illustrates how the world was governed by a two-pole structure rather than by a single dominant power or by total isolation. This bipolar arrangement persisted until the USSR’s dissolution in 1991, after which the balance of power shifted. The other descriptions don’t fit because there wasn’t a single overarching hegemon, there wasn’t an anarchic system with no organized order, and there wasn’t a global empire overseeing the entire world.
