PRINCETON, NJ -- Americans express mixed views on how Osama bin Laden's demise will affect U.S. national security, according to a Monday night USA Today/优蜜传媒poll. A slight majority (54%) believe bin Laden's death will make the U.S. safer from terrorism, nearly double the 28% who fear it will make it less safe.

Despite this optimism about the broad impact of bin Laden's death on U.S. national security, more Americans believe an act of terrorism is imminent than have said so at any time since the start of the Iraq war in 2003. Overall, 62% think an act of terrorism is either "very" or "somewhat likely" to occur in the U.S. in the next several weeks, with 17% considering it very likely. The current results indicate Americans are slightly more likely to be worried about a terrorist incident occurring than they were , but are less worried than at the start of the Iraq war as well as immediately after 9/11.

Although the U.S. Homeland Security department has not raised the U.S. terror alert level after Sunday's killing of bin Laden, security has been beefed up in New York City and several other high-risk terrorism targets out of retaliation concerns. The killing has also sparked much speculation about whether bin Laden's demise will result in the rise of successors even more intent on harming the West or, alternatively, lead to the splintering and weakening of terrorist groups.

Amid these debates, fewer than 4 in 10 Americans, 39%, say bin Laden's death makes them feel "a lot more confident" that the U.S. can succeed in the war against Islamic terrorism. Another third are "a little more confident."

Underscoring their continued concerns about the threat of terrorism, more Americans say the U.S. still has important work to do in Afghanistan and should maintain its troops there than believe the U.S. has accomplished its goals there and should call its troops home, 52% vs. 45%.

These preferences about the U.S. military presence in Afghanistan are consistent with the slight support . At that time, 53% said sending military forces to Afghanistan had not been a mistake, while 42% disagreed.

Slight Majority Impressed by Obama's Commander-in-Chief Display

As details about the Navy SEAL raid that killed bin Laden and the role President Obama played continue to emerge, Americans at this stage report feeling somewhat more positive about Obama's leadership of the military as a result. A third say the death of bin Laden makes them feel a lot more confident in Obama as commander in chief and another 21% say it makes them a little more confident. Fewer than half, 43%, are no more confident.

Most Democrats are now more confident in Obama on this measure -- either a lot or a little more -- while most Republicans say they are not more confident. Independents are closely divided, at 51% more confident and 44% not more confident.

The overall percentage saying bin Laden's death gives them a lot more confidence in Obama as commander in chief is similar to the 35% in the same poll for the success of the mission.

Bottom Line

While fearful that a retaliatory attack could be imminent, Americans are guardedly optimistic about the longer-term national security ramifications of the dramatic U.S. military operation that killed al Qaeda leader bin Laden at his residence in Pakistan.

Americans are twice as likely to consider the United States safer rather than less safe as a result. However, they continue to believe the U.S. military presence in Afghanistan -- initiated in October 2001 to destroy al Qaeda terrorist training camps -- is needed. And they have fairly modest views about what the U.S. military's success at locating and killing bin Laden means for the war on terrorism more generally. Although three-quarters say their confidence that the U.S. will win that war is at least somewhat higher as a result, fewer than half, 39%, say it makes them a lot more confident. Similarly, not quite a third of Americans, 32%, say bin Laden's death gives them a lot more confidence in Obama as commander in chief.
