Today our nation faces several major challenges, ranging in type from the conflict in Iraq to changes in force size and structure. These challenges may be more significant than any the United States has faced in more than a decade. With the publication of the 2007 KSIL, the Strategic Studies Institute and the U.S. Army War College invite all researchers to contribute their efforts to resolving these challenges. Researchers are encouraged to contact any of the SSI points of contact, or those found in the Expanded KSIL, for further information regarding their desired topics. These points of contact are not necessarily subject experts, but can recommend such experts or additional sponsors.
