NEW ORLEANS (WVUE) - The threat of terrorism was the subject of Tuesday's Republican presidential debate in Las Vegas.
"Protecting the homeland, destroying ISIS, rebuilding the fence - these are all the things that we need to focus on," former New York Gov. John Kasich said.
"I think we defeat terrorism by showing them that we do not fear them," U.S. Sen. Rand Paul said. "I think if we ban certain religions, if we censor the Internet, I think at that point the terrorists would've won."
"I'm a former prosecutor. I fought terrorists and won. When we get back in the White House, we will fight terrorists and America will be safe," New Jersey Gov.Chris Christie said.
Donald Trump remains at the top of the latest polls with a double-digit lead over the rest of the field. He focused his attention to keeping Muslims out of the country and deporting many who have recently come to the U.S.
"Tens of thousands of people having cell phones with ISIS flags on them? I don't think so. They're not coming into this country, and if I'm president and if Obama has brought some to this country, they are leaving. They are going," Trump said.
Former Florida Gov. Jeb Bush lashed out at Trump's plan, calling it and the candidate "dangerous."
"It will push the Muslim world and the Arab world away from us at a time when we need to engage with them and to be able to create a strategy to destroy ISIS. Right now, Donald is great at one-liners, but he's a chaos candidate and he'd be a chaos president," Bush said.
Candidates Carly Fiorina and U.S. Sen. Marco Rubio believe defeating ISIS is a technology race.
"The Patriot Act was signed in 2001 roughly. The iPhone was invented in 2007. The iPad was invented in 2011. Snapchat and Twitter and all the rest of it happened around just several years ago. Technology has moved on and the terrorists have moved on with it," Fiorina said.
"I promise the next time there is an attack on this country the first thing people are going to want to know is why didn't we know about it and why did we stop it," Rubio said. "The answer better not be we didn't have access to records or information that would've allowed us to identify those killers before they attacked us."
Ben Carson and U.S. Sen. Ted Cruz said they believe the problem with ISIS starts with political correctness.
"People are worried about being seen as an Islamaphobic. This is crazy because we are at war. That's why I ask Congress to go ahead and declare the war," Carson said.
"What the Obama administration keeps getting wrong is whenever anything bad happens they focus on law-abiding citizens instead of focusing on the bad guys. We need to focus on radical Islamic terrorists," Cruz said.
Republicans have seven debates scheduled by March 2016.
