Which event led to tensions between Germany and France during the World Disarmament Conference?

The event that led to tensions between Germany and France during the World Disarmament Conference was Germany's rearmament plans. Following World War I, Germany was subject to the Treaty of Versailles, which heavily restricted its military capabilities and overall military strength. The rearmament plans signified Germany's intention to strengthen its military forces, which was perceived as a direct threat by France, still wary of German aggression after the devastation of the war. This situation heightened tensions as France sought to maintain the security of its borders and viewed Germany's actions as a violation of the post-war peace agreements. The World Disarmament Conference, which aimed to address disarmament and promote peace, became a focal point for the conflicting interests of the two countries, ultimately contributing to the deterioration of their relationship during this critical period.
