The author briefly examines the European response to the changing security environment and the opportunities presented by the European Security and Defense Policy Expeditionary Force. As he correctly observes, the establishment of a European expeditionary force will be no easy matter, will require substantial investment, and will take years to complete. However, it is the right course for Europe to take. The European Union (EU) cannot manage emerging security issues using Cold War legacy forces because they are too ponderous to deploy. A lighter, more nimble expeditionary force is critical to EU policy. The author also points out that the United States must remain involved in the EU initiatives. Europe cannot go it alone and will need advice and perhaps even material support if it is to realize its ambitious agenda.
