What changed between 1994 and 2003?

I know this video is about the first Gulf war, but what changed between then and 2003? To me, this is just unbelievable and so hard to watch!
Because of "bad intelligence", we have now lost 3,921 Americans as of today! In 1994, the administration thought 146 American lives lost was a bad number. What about now?
I know I'm not really stating anything new about the excuse given to take us to war in 2003. Isn't it about time someone admits there is nothing that can be done to establish a new government in Iraq? Isn't it about time someone stops the senseless killing of our soldiers?
Let me quote the article below - "Dishonest." "Reprehensible." "Corrupt." "Shameless."

Fight or Flight?
Cheney's weak argument in the war debate.

"One might also argue," said Vice President Cheney in a speech on Tuesday, "that untruthful charges against the Commander-in-chief have an insidious effect on the war effort." That would certainly be an ugly and demagogic argument, were one to make it. After all, if untruthful charges against the president hurt the war effort (by undermining public support and soldiers' morale), then those charges will hurt the war effort even more if they happen to be true. So, one would be saying, in effect, that any criticism of the president is, essentially, treason.
Lest one fear that he might be saying that, Cheney immediately added, "I am unwilling to say that"—"that" being what he had just said. He generously granted critics the right to criticize (as did the president this week). Then he resumed hurling adjectives like an ape hurling coconuts at unwanted visitors. "Dishonest." "Reprehensible." "Corrupt."
"Shameless." President Bush and others joined in, all morally outraged that anyone would accuse the administration of misleading us into war by faking a belief that Saddam Hussein possessed nuclear and/or chemical and biological weapons.
