MADISON, Wis., Feb. 1 (UPI) -- Wisconsin Gov. Scott Walker, a possible contender for the 2016 presidential election, discussed his approach to foreign policy on Sunday, telling ABC's This Week that the United States should be "prepared to put boots on the ground" in Syria.

Walker stressed the need for an "aggressive strategy" against the Islamic State, also known as ISIS or ISIL, a terror group that has seized large swaths of land in Syria and Iraq.


"It's not a matter of when they attempt an attack on American soil, or 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," Walker said.

"We have to be - go beyond just aggressive airstrikes," he said. "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."

Walker, who also said Americans want leaders with "big, bold ideas," is leading potential Republican candidates in the battleground state of Iowa, according to a new poll.
