Are the wars in Ukraine and between the US and Iran showing the limits of global powers?

A recent publication explores whether the ongoing conflicts—Russia's war in Ukraine and the military confrontation between the United States and Iran—indicate limits to the influence and power of global superpowers. The article specifically focuses on Russian attacks on Kyiv, one of the epicenters of the war, as well as the overall state of both conflicts. The authors analyze the extent to which even the most powerful nations can achieve their objectives in prolonged and complex armed confrontations. Despite significant military technology and resources, these wars may highlight the boundaries of what superpowers can accomplish through force. The publication does not merely describe events but poses a fundamental question about the future of global power structures. It invites reflection on whether the traditional concept of military superiority remains valid in today's international arena, where local resistance and international pressure can constrain even the largest actors.
