The Great Unasked Question

Two U.S. Airmen were killed today in a shooting at Germany’s Frankfurt Airport. The great question that I don’t hear being asked is simply this: What are members of the American military still doing in Germany when WWII ended in 1945? Instead of feeling up U.S. citizens at U.S. airports, perhaps the TSA should instead provide security for foreign buses transporting U.S. military personnel.
