The Soviets take your inaction for a sign of weakness. They seize and blockade West Berlin. Additionally, much of Latin America also sees your inaction as weakness and chooses to align itself with the Soviet Union instead of the United States, and in just a few years you lose the Cold War. The United States loses its position as a global superpower as the Soviet Union becomes the hegemon in a unipolar system. While you avoided nuclear war, you did so at the cost of the US global power, influence, and prestige.
