An overwhelming majority of polled Americans supported Sunday's military strikes in Afghanistan even though most believe they will provoke more terrorist attacks in the United States.

The ABC News-Washington Poll telephone survey conducted after the start of Sunday's air strikes found 94 percent saying they support the military action, with 83 percent saying they "strongly" support it.

A large majority, 82 percent, said they expect a long conflict. Also, 71 percent said they support President Bush's call for entering a broad war against terrorism and not limiting the attacks to those behind the Sept. 11 attacks on the World Trade Center and Pentagon.

More than three-quarters said they would support sending "a significant number" of U.S. ground troops into Afghanistan to capture or kill Usama bin Laden and his followers.

The poll found that 55 percent of Americans believe the air strikes will increase the likelihood of further terror attacks against the United States. However, by a margin of nearly 3 to 1, the public believes the risk created by the military action is smaller than the risk that would be created if the United States and its allies did not take the action.

The survey found that 93 percent of those questioned approved the way the president handled the situation; 14 percent said Bush should have done more to find a diplomatic solution before resorting to military action.

The poll was conducted Sunday among a random sample of 506 adults and has a 4.5-point error margin.
