How did the Romans make sure that there would never be another war with the carthans?

After the defeat of Carthage in the Third Punic War (149-146 BCE), the Romans enacted measures to ensure there would be no future conflicts with the Carthaginians. They completely destroyed the city of Carthage, razing it to the ground and salting its fields to prevent any resurgence. Furthermore, they imposed strict limitations on any potential revival of Carthaginian power, including prohibiting the establishment of a new city in the same location. This effectively eliminated Carthage as a military threat and solidified Roman dominance in the region.
