President Barack Obama announced Wednesday his plan to combat ISIS. Actions will include U.S. air strikes and supporting existing forces on the ground.
The group is unique in its brutality, he said, targeting women, children, journalists and religious minorities.
So far, thousands of would-be terrorists from around the world - including Europe and the U.S. - have joined ISIS, he said. Any of them could attempt to return to their homes and carry out attacks.
His strategy was made up of four parts.
1. U.S. airstrikes: Obama said such attacks have already been successful against al-Qaeda in Iraq, Yemen and Somalia.
2. Support to foreign ground forces: He vowed to send 475 more U.S. troops to Iraq to support local security forces as well as provide military equipment and training to Syrian rebels.
3. Counterterrorism: The U.S. will work with allies on intelligence and programs to prevent foreign fighters from joining ISIS.
4. Humanitarian assistance: Aid will go to Muslim, Christian and religious minorities in danger of being driven out of their homes by ISIS.
