WATCH: Trump travels to Milwaukee to discuss race relations and law enforcement
'You need a lot of things'
Donald Trump says his plan to heal relations between law enforcement and minority communities begins with a respect for police, tougher law-and-order tactics, extensive community dialogue and economic growth that can generate jobs for frustrated inner-city neighborhoods.
"What you really have to do is you have to get people to get along. You have to do a system with a lot of things. And you need jobs. You need a lot of things," Trump said in an interview with Circa Tuesday night in Milwaukee.

'You have to have law and order'
Trump spoke just a few short miles from city streets scarred by rioting last weekend after a policeman shot and killed a young black man fleeing a traffic stop. The police say the suspect had a handgun and refused an order to drop his weapon.
"You have to have law and order. We have to respect our police. And if that is not done, we don't have a country," he added. "You have to work together with the community, with everyone in the community. But then again, you have to have law and order."

Federal rating system
Trump said he also was studying ideas like creating a federal rating system to flag communities where relationships between police and minorities are improving, and target other areas before relations escalate to strife and violence.
"A lot of people are looking at that, and so are we," he said.
WATCH: Trump says the UN 'has not been effective' but can still play role
UN 'not very effective'
Trump began the week with a major address on terrorism. After Tuesday's Milwaukee speech, Trump indicated the United Nations could play a role in his foreign policy, but only if it steps up its game.
Trump also stressed his foreign policy would use military force far more judiciously than Hillary Clinton did in Libya or Dick Cheney did when pushing to oust Saddam Hussein in Iraq.
'ISIS is pretty much having it now'
"Libya was certainly a mistake because they went about it the wrong way, and in fact they should have at least kept the oil. They didn't keep the oil. And that is some of the finest oil in the world and we didn't do it. Frankly ISIS is pretty much having it now," he said.
"Everything she has done has been a mistake," Trump said of his Democratic opponent. "You almost can't think of nothing that Hillary Clinton has done that has worked out well. Her running for president, her becoming president would be a disaster."
'Honored' by Cheney endorsement
Pressed to assess Cheney's advocacy for the Iraq war, Trump said: "I was always against going into Iraq. I never wanted to go into Iraq. I was honored to get the endorsement of Dick Cheney, but I would have not gone into Iraq."
Trump said it was too early to craft a plan for what to do in Syria and Iraq until ISIS was defeated.
"We have to make sure -- let's defeat ISIS first, before we do anything else, and start thinking about too much after," he said. "We have to defeat ISIS, and we will."
'Big role' for Giuliani in Trump administration
On his latest campaign leg, Trump brought along former New York City Mayor Rudy Giuliani, himself a former presidential candidate, and declared there would be a "big role" for his fellow New Yorker in a Trump presidency.
He said he would model some of his own law-and-order policies after those Giuliani championed when he drove down crime rates a decade ago in America's largest city.
"They were effective. They had a great effect. And when you look statistically they certainly had a great effect," he said.
