What are the Advantages and disadvantages of arms race?

The advantages of an arms race can include increased national security and deterrence against potential aggressors, as nations may feel compelled to bolster their military capabilities to protect their interests. However, the disadvantages are significant, including the potential for heightened tensions and conflict, as well as the diversion of resources from essential domestic needs to military spending. Additionally, an arms race can lead to instability and an escalation of hostilities, increasing the risk of war. Ultimately, while it may provide a sense of security, it often exacerbates global insecurity.
