Petraeus: 'A Lot of Soul Searching'

July 31, 2007 — -- Many Americans have said they want the United States to withdraw troops from Iraq.

In fact, a July 21 ABC News poll said 60 percent agree with the idea. It's a point of public contention that Gen. David Petraeus, the top commander in Iraq, said he definitely is aware of.

Petraeus' report on Iraqi progress, due in September, could play a vital role in determining how long American troops stay.

"We're going to be engaged in Iraq for some foreseeable future," he said during an exclusive interview on "Good Morning America" today. "I don't think anyone would think that we'd be completely out of here or completely unhooked from Iraq."

"And I think frankly that the American people, if they have a sense of this, can succeed because they know the stakes here. This is an extremely important endeavor."

But as the war trudges into its fifth year, the optimism some Americans previously held onto has faded. In 2004 Petraeus graced Newsweek's cover, and many reports at the time talked about an increasing momentum with huge progress. But the commander said he is no longer as optimistic.

"I'm not an optimist or a pessimist, I'm a realist," Petraeus said. "I think we've learned over the years. We've had our moments of optimism, and frankly some of those moments were in that particular summer as we headed toward the elections. And we remember the purple finger moments and the wave of optimism that accompanied the elections and some of the other moments of progress. Sadly, a lot of that was undone by the horrific sectarian violence."

Troops in Iraq are operating in an environment where, during the last winter, the very fabric of Iraqi society was torn, he said. Petraeus said he was aware of the challenges in Iraq and how difficult the situation is, but he doesn't believe it is hopeless.

Even as Petraeus attempts to renew the public's faith in the war, other officials are beginning to show their emotions publicly. Recently, Defense Secretary Robert Gates broke down at a podium when he talked about the death of Marine Maj. Douglas Zembiac, who was known as "the lion of Fallujah."

"Every evening I write notes to the families of young Americans like Doug Zembiac," Gates said as his voice choked up. "They are not names on a press release or numbers updated on a Web site. They are a country's sons and daughters."
