The International System and a Post 9/11 World
9/11 has had an immense impact on the international system. A system is characterized as an assemblage of units. A change in one unit causes a change in all the others. When America was attacked in 2001 there was a tremendous change in the country, especially in homeland security and foreign policy. This change forced many other countries to comply with the US’s change. For example, and British person flying into the US from the UK would HAVE to plan ahead and comply with the new airline restrictions. In turn, this is has had a domino effect. Airline travel in many other countries is currently as strict (if not more strict) than post 9/11 US. A liberal analyst would say that the UK and country’s other air travel restrictions were put in place because they learned a lesson not only from the misfortune brought upon the US but also their strict regulations after the incident. This also makes clear the implicit notion of the shared interest of these countries to keep hijackers and terrorists off their airplanes. The interdependence of air travel across states and borders has forced these international parties to influence and change policies in other countries.
