Donald Trump stirred a Knoxville crowd Monday night with a lively speech that took aim at terrorists, current leaders and foreign governments such as China.

"We're going to make our military so strong, no one is going to mess with us," the GOP candidate said.

At another point, when pondering any possible attack against the U.S., he declared, "I'm going to bomb the ... out of them. I don't care."

Radicalism and terrorism were the topics of the day, the billionaire said, alluding to Friday's Paris attacks.

“Radical Islamic terrorism, let’s talk about it, we have no choice," he said.

Trump also declared he would halt the crush of immigrants fleeing from the Middle East and Africa for Europe.

He was introduced Monday night by 92-year-old Beada Corum, who registered to vote for the first time in her life so she could cast her ballot for Trump. She decided to become a voter after seeing him on TV. What he said, Corum told WBIR, "makes a lot of sense to me.”

Protesters chanted and held signs outside the convention center. The candidate's stance on immigration prompted many to come.

Although it’s unlikely he was an unknown to any, for many East Tennesseans this was a first chance to see him in person. And some said they needed more substance.

“You know he really gets everybody going, I like how he motivates everybody but I’d definitely like to hear some more policy from him,” said Brett Pippin, a University of Tennessee student from Sevier County.

Trump appeared about 7 p.m. and spoke for about an hour. He also spent several minutes shaking hands in the crowd afterward.

Eager crowds had begun gathering hours beforehand. Doors opened at 4:30 p.m.

This was Trump's third campaign stop in Tennessee since the end of August.

He arrived shortly after 6 p.m., tweeting: "Just landing in Knoxville, Tennessee! Massive crowd expected! Will all have a great time, despite serious subject matter."

Trump said over the weekend the terror attacks in Paris would have been "a much, much different situation" if the victims were armed with guns. He spoke at a rally in Beaumont, Texas, on Saturday about gun control in light of the Paris attacks.

Before speaking, Trump held a moment of silence in honor of the victims.

The businessman said the U.S. would be "insane" to accept any refugees from Syria after the attacks.

He also criticized President Barack Obama's handling of the Islamic State group saying the U.S. should be more aggressive.

He has called for the U.S. to destroy the oil fields controlled by ISIL.
