The opposite of "arms reductions" would be "arms buildup" or "arms proliferation." While "arms reductions" refer to the process of decreasing the amount of military weaponry and equipment, "arms buildup" is the opposite, referring to the increase in arms and ammunition. "Arms proliferation," on the other hand, refers to the spread and escalation of arms in arms race scenarios, which is the opposite of "arms reductions." Many people argue that "arms proliferations" results in more conflict and violence, while "arms reductions" help reduce tension and enable peaceful negotiations. Therefore, it is crucial to focus on arms control rather than arms proliferation, and promote a safer and peaceful world.
