Wisconsin Gov. Scott Walker says a recent trip to Israel reminded him of post-September 11 America, claiming that the daily lives of Israelis resemble American life in the aftermath of the 9/11 attacks.

Walker spoke Saturday to Iowa Republicans in West Des Moines after returning from his recent trip to Israel.

“Remember for a moment how many of us—the young people don't remember this probably so well—but those of us as adults remember what we felt like on the day after Sept. 11,” the Wisconsin governor said. “That's how they feel almost every day. That's what they feel like because of what they're dealing with.”

The potential 2016 presidential candidate added that the trip reinforced his belief that the United State must aggressively deal with terrorists abroad.

Walker criticized President Barack Obama's foreign policy, which he says has been to "draw a red line in the sand and allow people to cross it." Walker says the United States should deal with terrorism head on and "take the fight to them."

Walker was to appear later Saturday at a dinner hosted by the Republican Party of Iowa. Walker has yet to announce his 2016 plans.
