Atomic bombs, maybe. Regular bombs, no. Drones, also no. If war meant thousands of American soldiers had to swordfight with thousands of Iranian soldiers and possibly get stabbed and die, instead of just flying planes overhead, we'd have a lot fewer wars. War is easy when you don't have to risk your life.
Looks at history…. There certainly weren’t a lot fewer wars back when people had to physically stab each other with swords. Quite the opposite?
Wars of the gunpowder age have been far more bloody. Far more destructive to civilian life. Far more lasting damage to the environment.
