North Atlantic Treaty Organization
Flag of the North Atlantic Treaty Organization (NATO).
The September 11 attacks served as a pivotal turning point for the North Atlantic Treaty Organization, fundamentally altering the alliance's operational focus. Following the attacks, NATO invoked Article 5 for the first time in its history, establishing a new dynamic that increasingly favored military engagement by member states outside of Europe.12
This shift led to a higher tempo of operations beyond the alliance's traditional geographic scope, most notably:
- Afghanistan: Beginning in the summer of 2003, NATO undertook a mission against Taliban forces in Afghanistan, which had provided a safe haven for al-Qaeda and its leader, Osama bin Laden.23
- Libya: In early 2011, the alliance conducted air operations against the regime of Muammar al-Qaddafi.2
These expanded missions revived long-standing debates regarding "burden sharing" among member states, as the increased operational requirements necessitated more equitable distribution of the costs and resources associated with NATO's global military commitments.2
