Weapon Synchronizer

The progress of civilization is inseparable from war, and what really affects war is weapons or human nature. Starting from the first broken stick, did humans influence the weapons, or did the weapons influence humans. When the development of weapons is no longer limited to existing technology, how does a war begin and end? When a weapon becomes a part of one's body, who is in charge? When an ordinary person suddenly has a weapon that can change his life, is he just facing a battle? When everything comes to an end, is it the people who control the weapons or the weapons that control the people? And is this so-called end point the end of the war or the beginning of the dispute?
