President Bush says he does not know what Iran was thinking when five small boats confronted U.S. Navy ships in the strategic Strait of Hormuz Sunday.

The boats, apparently operated by Iran's Revolutionary Guard Corps, veered away from the three U.S. ships after dropping boxes in their path. President Bush says it was a provocative act that should not be repeated.

"It is a dangerous situation, and they should not have done it. Pure and simple," he said.

Iran says the confrontation was ordinary and suggests it may have been a case of mistaken identity.

But he begins his eight-day trip in Israel and the West Bank in separate meetings with Israeli Prime Minister Ehud Olmert and Palestinian President Mahmoud Abbas.

Mr. Bush is hoping to further encourage talks toward a separate Palestinian state that began less than two months ago in Annapolis, Maryland. The president says an outline for a separate Palestinian state is crucial for political moderates who are battling forces of extremism.

"They need to have a vision that is clearly defined that competes with the terrorists and the killers who murder the innocent people to stop the advance of democracy," he said.

During his trip, the president will meet with U.S. military and political leaders from Iraq, speak with women's groups in Kuwait, and visit Israel's Holocaust museum in Jerusalem.
