How might the Cold War have progressed if the U-2 incident had never occurred?

If the U-2 incident had never occurred, the Cold War might have progressed with less tension and hostility between the United States and the Soviet Union. The lack of the incident could have prevented the deterioration of diplomatic relations that followed, possibly allowing for more effective negotiations and arms control agreements. Additionally, it may have reduced the public perception of espionage as a significant threat, potentially leading to a less confrontational approach in both countries' foreign policies. Overall, the trajectory of the Cold War might have included fewer crises and a more stable geopolitical environment.
