Iraq entered U.S. politics once again on Friday as American forces launched strikes on ISIS militants, a move that won't sit well with many Americans, 50 percent of whom don't believe it's the U.S.'s responsibility to assist the Iraqi fight against insurgents. More than 70 percent of Americans say the Iraq war wasn't worth it, which is why Obama stressed Thursday that the intervention there would be limited. Some Republicans have called for further action in Iraq, while more libertarian-leaning members of the party are advocating for restraint.
