The unfolding meaning of 9/11

For anyone who lived through it, 9/11 will always be one of those "I will never forget where I was" moments. Four crashed planes, nearly 3,000 dead. After twenty years, the poison of the time-release horror is still as toxic as ever, is still spreading, is still history-in-the-making.

A Pearl Harbor moment, with the expectation of a World War II kind of victory to follow. Was it WW2? Or Vietnam? "Our war on terror begins with al Qaeda, but it does not end there."
