Gary E. Luck
He was a Senior Fellow for the National Defense University in support of the Pinnacle, Capstone, and Keystone programs.In addition, Luck attended numerous military schools and courses, to include the Armor Basic and Advanced Officer courses, Army Aviator training, the Armed Forces Staff College, and the United States Army War College.Luck warned President Bill Clinton that a renewal of the Korean conflict would cost "A million, a hundred billion, and a trillion," meaning 1 million American casualties, $100 billion in economic costs to the United States, and $1 trillion in industrial damage to South Korea.The crisis was ultimately defused by the successful negotiation of the USA-DPRK Agreed Framework, but North Korea eventually acquired nuclear weapons.[4] After his retirement from the Army, Luck served in a variety of senior advisory positions in support of the United States Department of Defense, overseeing exercise control during Exercise Millennium Challenge 2002, and as an advisor to then-Commander of United States Central Command, General Tommy Franks, prior to the US led invasion of Iraq in 2003.
