... GEN George Casey. Military historians and other security studies scholars will long debate what GEN Casey did or did not do in Iraq from 2004 until 2007, but that is not the purpose of this post. Many people know that GEN Casey began his military service in 1970 about a month before his father, MG George Casey Sr., became the highest ranking U.S. officer to die in Vietnam. GEN Casey's military career ended yesterday as his family dealt with another loss -- the death of GEN Casey's grandson. My heart and prayers are with the Casey Family in their time of grief, and I salute a dedicated public servant for a lifetime of selfless service to our nation.
