PRINCETON, N.J. - March 17, 2006 (UPI) -- Support for the Iraq war has fallen in the past three years as a CNN/USA Today/Gallup poll shows 60 percent of U.S. respondents now say the war wasn't worth it.

In March 2003, just after the invasion of Iraq began, 29 percent of those asked said it was not worth it to go to war.

Telephone interviews with 1,001 adults nationwide conducted March 10-12 found 22 percent of respondents felt the United States would "certainly" win the war. In March 2003, 69 percent expressed that amount of confidence.

In 2003, by 73 percent to 24 percent, poll respondents said the war was morally justified, but today the public is divided, with 47 percent saying it is morally justified and 50 percent saying it is not.

When no weapons of mass destruction were found in Iraq, a Gallup poll showed most people rejected the charge that the Bush administration deliberately misled the public about the matter by 67 percent to 31 percent. In Friday's results, a slight majority, 51 percent to 46 percent, believes the Bush administration deliberately misled the public.

The poll has a margin of error of 3 percentage points.
