We Will Act if Islamic Group Threatens US: General Dempsey

General Martin Dempsey says he will recommend the U.S. military move directly against Islamic State militants in Syria if and when he determines they have become a direct threat to the U.S. homeland or Europe.

But the chairman of the Joint Chiefs of Staff says he still believes the insurgent group is more a regional threat and is not plotting or planning attacks against either the U.S. or Europe.

Dempsey says he believes that key allies in the region - including Jordan, Turkey and Saudi Arabia - will join the U.S. in helping to quash the Islamic State group.

So far, the Obama administration has restricted its military action against the militants to specific operations within Iraq.
