"NATO and Terrorism" posits that the post 9/11 war on terrorism has had a profound effect on NATO's post Cold War structure and military missions. "NATO and Terrorism" focuses on the decades from 1989 until 2009, during which NATO underwent two major transformations. The first was the expansion from sixteen to twenty-six member states. This section traces the evolution of the new member states from communist enemies to democratic partners, looking at their differences and similarities, the reactions of their publics to membership, and their involvement in NATO activities. The second was the radical shift in the missions of the alliance and the book analyzes the military operations in Bosnia, Kosovo, Afghanistan, and Iraq as well as the new issue of the Missile Shield for Europe. Both sections also look at how inclusion of more states is predicated on the conclusion that their geopolitical position makes them a barrier against terrorism centered further east and how the missions involve the struggle against several varieties of terrorism.
