What events could have gone drastically differently if modern technology existed at the time they took place?

There are many events throughout history that could have had significantly different outcomes if modern technology had been available at the time they took place. Here are a few examples:

World War II: Modern communication and transportation technologies, such as satellite communication and jet airplanes, could have enabled faster and more effective coordination among the Allied forces. This could have resulted in a quicker and more decisive victory over the Axis powers. The Kennedy assassination: Modern forensic technologies, such as DNA analysis and advanced ballistics testing, could have provided more conclusive evidence in the investigation of President Kennedy’s assassination. This could have led to a clearer understanding of what happened and who was responsible. The sinking of the Titanic: Modern navigation and communication technologies, such as radar and satellite phones, could have enabled the Titanic to avoid the iceberg that ultimately caused the ship to sink. This could have resulted in many lives being saved. The spread of diseases: Modern medical technologies, such as vaccines and antiviral drugs, could have prevented or slowed the spread of many deadly diseases throughout history, such as smallpox, polio, and HIV/AIDS. The exploration of space: Modern rocket and space travel technologies could have enabled earlier and more ambitious space exploration missions, such as manned missions to the moon and beyond. This could have resulted in significant advances in our understanding of the universe and our place in it.
