In the aftermath of the deadly terrorist attacks in Paris, Republican presidential candidates came out strongly, calling for changes in foreign policy and a stronger military response to the Islamic State.

Leading candidates such as Donald Trump, Marco Rubio and Ted Cruz, all responded with strong language and extreme proposals after the attack.

Donald Trump

Republican front-runner Trump suggested shutting down mosques in the U.S. to somehow prevent potential terror strikes.

"Well, I would hate to do it but it's something you're going to have to strongly consider," Trump said in an interview with MSNBC. "Some of the absolute hatred is coming from these areas. ...The hatred is incredible. It's embedded. The hatred is beyond belief. The hatred is greater than anybody understands."

Marco Rubio

Sen. Marco Rubio, R-Fla., called the attacks a "wake-up call." He said that the Islamic extremists wanted to replace American society with a "Sunni Islamic view of the future."

"They hate us because of our values. They hate us because young girls here go to school. They hate us because women drive. They hate us because we have freedom of speech, because we have diversity in our religious beliefs. They hate us because we're a tolerant society," said Rubio, via the Guardian.

Ted Cruz

Sen. Ted Cruz, R-Texas, a candidate who's popularity has risen given it's good showing in recent presidential debates, criticized President Barack Obama and Democratic presidential candidate Hillary Clinton's willingness to accept Syrian refugees into the country, calling it "lunacy."

Carly Fiorina

According to CNN Politics, former Hewlett Packard CEO Carly Fiorina entertained the idea of having a summit with Arab nation allies to combat ISIS. She suggested arming the Kurdish Peshmerga forces, who recently recaptured the city of Sinjar from ISIS militants with the aid of U.S. air support.

Ben Carson

Perhaps one of the most radical approaches was proposed by candidate Ben Carson, who is currently closing ground with Trump in the polls. He said he would defund all programs that allowed Syrian refugees into the country, "immediately." He also criticized Obama's reluctance to bring ground troops into Syria.

"As president, I would give the mission to the Pentagon and ask them what they need to accomplish the mission," said Carson at a news conference on Sunday. "The era of arm-chair quarterbacking our military will end in my administration."

Jeb Bush

Former Florida Gov. Jeb Bush also criticized Obama's policies, saying the president was more concerned with closing Guantanamo Bay than in implementing a stronger strategy against ISIS.

USA Today reports Obama wasn't deterred by Republican criticisms, stating, "if folks want to pop off and have opinions about what they think they would do, present a specific plan."
