(CNSNews.com) - "You call yourself a counterpuncher...Would you be doing late-night Twitter wars with world leaders who insulted you?" ABC newsman Jon Karl asked Republican Donald Trump Sunday on "This Week."
Trump responded that Twitter is a "very effective" way of communicating. "I've been very effective with it. I have, between that and Facebook, I have like 15 million or 16 million followers. It's a great way of communicating. Now other people don't like it because they have 15 followers. I have, between that and Instagram, I have probably close to 16 million followers.
"And, frankly, it's a great way of communicating as far as I'm concerned. But I'm not going to be doing it very much as president.
"I will say you know, I will -- I will act in the best interests of our country. I will act to protect our country, whether that's counterpunching or not.
Our country's going to be protected -- not like it is now, where we have nobody at the helm, where we have nobody protecting the interests of our country, where we're being ripped off by every single nation in the world and we can't even beat ISIS at war.
Turning to the terror attacks in Brussels, Karl asked Trump if he thinks Europe is a safe place for Americans to travel.
"I don't think America is a safe place for Americans, you want to know the truth," Trump responded. "I don't think England or -- I don't think that Europe is a safe place. No, I don't. I think there are a lot of problems in Europe that are very, very severe, weak, you know, the -- lots of the free world has become weak. When you look at Brussels, when you look at the way they've handled things from law enforcement standpoints, when you look at Paris, when you look at so many other places, no. It's not.
"But neither is the United States a safe place because we're allowing thousands of people to come in here; nobody knows where they're from. Nobody knows who they are. And they're coming in here by the thousands.
"And let me tell you something, we're going to have problems just as big or bigger than they've got."
