In the wake of ISIS releasing a new video that shows the horrific beheading of British aid worker David Haines, Rep. Buck McKeon (R-Calif.), chairman of the House Armed Services Committee, joined Maria Bartiromo on Sunday Morning Futures today to discuss President Obama's plan to take on the brutal terror group.

McKeon said this shows the ruthlessness of ISIS and drives home the point that half-measures will not work.

"We have to go after them and go after them hard," he stated, adding that he thinks Obama's plan is a good start, but he should be much more robust in putting boots on the ground.

"We already have boots on the ground. We just have to make sure we have enough to give Iraq the support they need to beat ISIL in Iraq," McKeon said.

"We need to finish them now," he warned. "Every day we wait, they grow stronger."

McKeon noted that our country is making significant military cuts, while, at the same time, asking our military to do more and more.

"We can't keep pushing them to do more without giving them the resources that they need," he said. "So, we've got to make up our minds. If we're going into this, we've got to do it full bore."
