The question is this: Why didn't Saddam Hussein retaliate immediately? Here are some possibilities:

- David Galbraith, political science professor at Brigham Young University: Saddam made a conscious decision to not strike back immediately."He was saving what he could to fight another day. He may just be waiting for the exact moment to release destruction. By not launching missiles, he has saved some of them."

Galbraith said it is also possible Saddam miscalculated and the United States was able to destroy many key points in his operation.

Saddam felt a lot of pressure not to be the first to attack, Galbraith said.

- Stan A. Taylor, professor and chairman of the political science department at Brigham Young University: "The most plausible explanation is the attack did what it was supposed to - destroy the command and control of the Iraqi army, which is modeled after the Soviet army. The Soviet army can't do anything without clearing it first with a general, whereas in the U.S Army, field commanders have some discretion (to act). They just couldn't communicate.

"Secondly, I think they destroyed some of the instruments with which they would do something. It's a testament to modern warfare."
