WASHINGTON Air Max 97 Black White Sale , Aug. 26 (Xinhua) -- The United States is worried about a possible future attack from the Islamic State terror group, but it remains unclear just how much of a threat the radicals pose to the country.
The group has in recent weeks been on the move in Iraq, overrunning vast swaths of territory in the country's north as the militants go on a killing spree. While Kurdish fighters backed by U.S. air power have had some successes against the Islamic radicals, they remain unchecked in neighboring Syria as the United States gears up to hit the radicals in that country as well.
The Islamic State poses a major problem for the United States, which aims to keep terrorism in check a decade after the Sept. 11 Air Max 97 Silver Sale , 2001 attacks on New York and Washington. The militants' territorial gains have Washington worried that its ultimate nightmare could come true -- that the group could carve out a haven in Iraq or Syria and use it as a staging ground for attacks against the U.S., much like al-Qaida did in Afghanistan.
But just how much of a threat the group poses at the moment remains unclear. Certainly it would like to attack the U.S. if it had the chance, experts say. But the group has its hands full in Iraq and Syria, and it's unclear just when and if an opportunity to hit the U.S. will present itself.
"When it comes to conducting attacks on the U.S. homeland, there needs to be both will and capability Air Max 97 Pink Sale , we're not sure there's certainty on either of those fronts at this point in time, but ... this doesn't mean the group won't develop the desire to strike the U.S. in the future, especially as things escalate on the ground," RAND Corporation associate political scientist Colin P. Clarke told Xinhua.
If the Islamic State did attack the U.S. homeland, it would likely be a major attack on the scale of those on New York and Washington that killed nearly 3 Air Max 97 Black Sale ,000 people from countries worldwide, he added.
"ISIS won't be satisfied with something perceived as impotent or unspectacular. This is a group that would want to pull off something along the lines of a 911 style attack, which could take years of planning," Clarke said, using another name of the Islamic group.
But right now the group is focused on creating a radical Islamic state in Iraq and Syria and wants to continue to hold and conquer territory that will push the group closer to its goal of establishing a caliphate there Air Max 97 White Sale , experts say.
