This paper delves into the challenges faced by the Taliban regime in Afghanistan, impacting their legitimacy and stability. These challenges encompass economic, humanitarian, and security issues similar to the previous Taliban regime from 1996 to 2001, along with new challenges arising from shifts in global security and politics. With a focus on international relations theory, specifically realism, the paper analyzes neighboring countries' responses to Taliban rule and their implications for regional security. Additionally, it examines potential spillover effects, such as increased terrorism and refugee flows. The paper advocates for a coordinated and multifaceted approach, considering the intricate political, social, and economic factors at play in Afghanistan. Emphasizing Pakistan's role due to its socio-cultural ties with Afghanistan, the paper encourages policymakers to involve governments, corporations, organizations, and international groups. Further research is necessary to develop effective strategies in addressing these challenges and promoting regional security and stability.
