Scott Walker told ABC that he would not rule out putting "boots on the ground" to fight ISIS:
"I think aggressively, we need to take the fight to ISIS and any other radical Islamic terrorist in and around the world. Because it's not a matter of when they attempt an attack on American soil -- not if, I should say, it's when -- and we need leadership that says clearly, not only amongst the United States but amongst our allies, that we're willing to take appropriate action. And I think it should be surgical," said Walker.
The ABC host asked, "You don't think 2,000 air strikes is taking it to ISIS in Syria and Iraq?"
"I think we need to have an aggressive strategy anywhere around the world. I think it's a mistake--"
"What does that mean. I don't know what aggressive strategy means. If we're bombing--I mean, we've done 2,000 air strikes. What is an aggressive strategy?"
"I think anywhere and everywhere, we have to go beyond just aggressive air strikes," said Walker. "We have to look at other surgical methods. And ultimately we have to be prepared to put boots on the ground if that's what it takes. Because I think you know--"
"Boots on the ground in Syria? U.S. boots on the the ground in Syria?"
"No, I don't think that is an immediate plan, but I think anywhere in the world--"
"But you wouldn't rule it out?"
"I wouldn't rule anything out. I think when you have the lives of Americans at stake and our freedom loving allies anywhere in the world, we have to be prepared to do things that don't allow those measures, those attacks, those abuses to come to our shores," said Walker.
