It's certainly true that the Department of Defense in general sees that as an area of growing strategic concern. It has the combination of instability and growing economic importance. Plus, it's a region where a number of states have conventional military power, thus testing FCS. But wargames simply select regions that are illustrative of future challenges rather than ones in which U.S. military intervention is planned or even likely. It just makes wargaming a lot easier if you have existing geography, demographic, and other information rather than having to make it up.
