Why was the growing military buildup in Europe prior to world war 1 is a cause of concern?

The growing military buildup in Europe prior to World War I heightened tensions among nations, as countries expanded their armies and navies in an arms race that created an atmosphere of fear and mistrust. This militarization made diplomatic resolutions more difficult and increased the likelihood of conflict, as nations were more inclined to rely on military solutions. Additionally, alliances formed in response to these buildups, such as the Triple Alliance and Triple Entente, further polarized Europe and set the stage for a larger, more devastating conflict when a crisis arose.
