The Vietnam-9/11 connection?

"There was another price to our withdrawal from Vietnam, and we can hear it in the words of the enemy we face in today's struggle -- those who came to our soil and killed thousands of citizens on September the 11th, 2001." Every time he thinks he's going to wake up back in the jungle...In a fit of self-serving revisionism, Dubya attempts to reinvent the lessons of Vietnam before the Veterans of Foreign Wars, arguing that our problems really began because we withdrew from Southeast Asia too early. (Also, apparently we lost the war because of Graham Greene's The Quiet American. So, on the bright side, it looks like Dubya is progressing along his high-school reading list.) As you might expect, this line of argument is not sitting well with many historians, among them the venerable Robert Dallek: "What is Bush suggesting? That we didn't fight hard enough, stay long enough? That's nonsense. It's a distortion,' he continued. 'We've been in Iraq longer than we fought in World War II. It's a disaster, and this is a political attempt to lay the blame for the disaster on his opponents. But the disaster is the consequence of going in, not getting out.'"
