I had read an article in Harpers "Easy chair: A letter to Barack Obama" by George McGovern. It presents the idea of bringing home the troops from the Middle East as well as from Korea and Europe--all good and logical ideas. Do people know that in 1963, the defense budget for $51 billion? And yet, neither China nor Russia threatens us.
Others have tried and failed to work their will in Afghanistan, such as Alexander the Great, the Mongols, the British and the Russians.
