Dr. John C. McManus, professor of history and political science at Missouri S&T and an expert in U.S. military history, says that troops on the ground – the “grunts” – not air strikes, have proven to be the crucial difference between victory and defeat in modern warfare. McManus has written 11 books on military history and is the historical advisor for a forthcoming PBS documentary titled “The American Road to Victory.” He is available to speak to the media regarding President Obama's plan for strategic actions to combat the extremist groups currently operating in areas of Iraq and Syria known as ISIS.
