How did the arms race increase rivalry between the great powers?

The arms race intensified rivalry among great powers by fostering a climate of suspicion and competition, as nations sought to outdo each other in military capabilities. This buildup of weapons and military technologies heightened fears of aggression, leading to preemptive strategies and alliances that further polarized relationships. As countries invested heavily in their arsenals, the stakes of international conflicts escalated, making diplomatic resolutions more challenging and increasing the likelihood of confrontations. Ultimately, the arms race contributed to a cycle of escalation that heightened tensions and solidified divides among rival powers.
