• In 2003, 83 percent of Americans said they were confident, 65 percent proud
• 61 percent of those polled now say it was not worth invading Iraq, poll says
• Support for Afghanistan war drops from 88 percent in 2001 to 53 percent today
WASHINGTON (CNN) -- Americans are starkly less confident and proud of their country's involvement in Iraq, according to poll results released Sunday.
However, the poll -- results of which were released on the eve of the Iraq war's 4-year anniversary -- also indicated that Americans are no more worried about the conflict than they were when it began in March 2003.
The CNN poll of 1,027 adults was conducted March 9-11 by Opinion Research Corp. The sampling error for the poll is plus or minus 3 percentage points.
According to the results, 35 percent of Americans are confident about the war, the poll said. When the war began, 83 percent of Americans expressed confidence in the campaign.
Similarly, 30 percent of those polled this month said they were proud of the war, as opposed to 65 percent who expressed that sentiment in 2003.
The poll also showed that 33 percent of Americans are afraid of the war and 55 percent are worried by it. Those percentages are roughly the same as they were four years ago.
Sunday's results came on the heels of a Saturday release indicating that years of war had whittled away at Americans' support for the conflicts in Iraq and Afghanistan.
When the Iraq war began, 68 percent of Americans said they felt the situation in the country was worth fighting over. Now, 61 percent of those surveyed say it was not worth invading Iraq, according to the poll.
That survey of 1,027 adults by Opinion Research Corp. was conducted by telephone March 9-11 as well. It has a sampling error of plus or minus 3 percentage points.
The poll showed that support for the Iraq war had dwindled to 35 percent. In 2004, support for the war was about 56 percent. Last year, the number dipped to 37 percent, and today about 35 percent of Americans say they support the war, according to the poll.
Support for the war in Afghanistan also has seen a considerable decline as 88 percent of those polled in 2001 said they were behind the conflict. This month's poll indicates that support lingers around 53 percent.
Also, according to the poll, about 55 percent of Americans feel the war in Afghanistan is "going badly," according to the poll.
