The two Germanies become one, and the Soviet Union does not object
What happened
Less than a year after the Berlin Wall fell, East Germany was formally absorbed into the Federal Republic on 3 October 1990. Gorbachev, withdrawing Soviet troops from East German territory, agreed not only to reunification itself but to a reunited Germany remaining a member of NATO, a concession few observers would have predicted from a Soviet leader just a few years earlier. Bush administration officials were initially cautious even to use the word reunification publicly, fearing hardliners on either side might yet derail the process before it was complete.
Why it matters
German reunification undid the single most concrete physical division the Cold War had created in Europe, and Gorbachev's willingness to accept a united, NATO-aligned Germany without a fight signaled to the world, more clearly than any speech could, that Soviet power over Eastern Europe had genuinely ended rather than merely paused.
How we know
The Two Plus Four Treaty settling Germany's international status, signed by both Germanies alongside the US, UK, France, and the Soviet Union, survives as a signed diplomatic document confirming the exact terms, including NATO membership, all five governments agreed to.
