The September 11 attacks fundamentally altered the global geopolitical order, prompting the United States to prioritize national security and move away from traditional multilateral roles. This shift included withdrawing from the Anti-Ballistic Missile (ABM) Treaty to develop missile defense systems, which caused international friction and led Russia to withdraw from the START II strategic arms reduction treaty.

In the decades following the attacks, international terrorism has acted as a “geopolitical accelerator.” Terrorist groups have demonstrated a capacity for large-scale violence that challenges state structures and creates insecurity transcending traditional borders. This era of terrorism has coincided with significant geopolitical adjustments, as existing international institutions struggle to manage phenomena that exceed their current capacity.
