WASHINGTON (AFP) - Ten years after 9/11, many Americans doubt they are winning the war on terrorism, according to a poll released Friday which shows the country split on whether the United States or extremists have the upper hand. The Gallup poll said 46 percent of respondents believe neither side is trumping the other, compared to 42 percent who argue the United States and its allies are winning, while just nine percent of respondents say the terrorists are ahead.
