Sadly there are some not-so-hopeful things that remain unchanged -- corporate greed (how delicious that by law, corporations are faceless and monolithic), income disparity, and endangered species among them.
You'd have to be Iraqi to see another rerun from pre-911. US-appointed Iyad Allawi, according to today's Sunday morning talking heads, wants to "take out Fallujah" before our election. Our military is supposedly more than ready to help him. I am reminded of the post-Desert Storm months when GHW Bush encouraged the Iraqis to overthrow Saddam, and Saddam grew in evilness by putting down that rebellion, creating mass graves we now seek.
It seems to me the Iraqi people haven't changed. They see Allawi, for plenty of reasons, as just another ruthless dictator appointed and supported by the US. Instead of the Republican Guard, he has the American military at his disposal to slaughter these dissidents.
The words in the Who's song apply equally well to the people of Iraq and the people of the United States. It may take a revolution here before the powers-that-be recognize that 9/11 didn't change everything.
"There's an old saying in Tennessee—I know it's in Texas, probably in Tennessee—that says, fool me once, shame on—shame on you. Fool me—you can't get fooled again."—George W. Bush, Nashville, Tenn., Sept. 17, 2002
