If the only thing that mattered was hard power, the Soviet Union would never have collapsed. What hard power forced the Soviets with their 10,000 warheads to retreat their border of control from Berlin all the way to the Belarus-Russian border? They had plenty of hard power, but the people stopped believing in communism. Therefore it collapsed. Solely due to soft power. Nobody forced the Soviets to collapse, they could have gone on indefinitely if they really wanted to. The Cold War was decided due to soft power.
Also, the British Empire allowed the US to overtake it as the world #1 power, solely due to soft power. Normally there should be a war between the British Empire to maintain its top level position against the rising US, but it never happened because the US had soft power in the UK in the form of cultural and political connections to forestall this. In the end, the British accepted the transition peacefully.
