BAGHDAD, Iraq (CNN) — Saddam Hussein, the former Iraqi dictator who spent his last years in captivity after his ruthless regime was toppled by the U.S.-led coalition in 2003, was hanged before dawn Saturday for crimes committed in a brutal crackdown during his reign.

Now that he is dead what is next? There have been many threats made about retribution against the United States and the current government of Iraq. Are we prepared, are we ready. I have a feeling that the world has now changed somehow. I feel that after this the world will look at the United States in a different way. What way I am not sure. I do know that I am worried about what is to come.
