Tomorrow War is a movie. Many people are picking it apart over brain-dead decisions. Some deserved. Others… I think… not. Basically, looking at the film, I think there were rules somebody made that did not make it to the screen. Rule number one appears to be that no person can exist twice in the same timeline. The soldiers who come back from 30 years in the future are less than 30 years old. They have not been born yet. And when the main character is scanned for suitability to go forward, he is confirmed to be dead in the future. Many people say that the surviving 500k people should just use the wormhole to retreat into the past and leave their dying future behind. But assuming a time paradox rule in effect, the leaders of the future cannot retreat to the past. They are stuck in a dying future, and help coming from the past is their only hope.
