    SEN. JOHN MCCAIN, R-ARIZ., PRESIDENTIAL CANDIDATE: Russia, as we know, also holds vast energy wealth. And this heavy influence in the oil and gas market has become a potential weapon that Russia is clearly prepared to use.

    NEIL CAVUTO, HOST: All right, Senator John McCain blasting Russia again today.

    My next guest says all this blasting and tough talk is not registering.

    With us now is Libertarian presidential nominee Bob Barr.

    So, you find Senator McCain's approach to this bad. Why?

    BOB BARR, LIBERTARIAN PRESIDENTIAL CANDIDATE: Well, it's very simplistic. Either that, or he really doesn't have a firm grasp of the geopolitics and the ethnic and demographic problems in that part of the world.

    He seems to feel, similar to what George Bush felt a number of years ago, that Putin could be trusted because he had looked into his eyes and saw a man he could trust.

    Senator McCain seems to be falling into that same simplistic mode that, if you meet somebody and know them, they're trustworthy, and we're their friend, and we need to support them.

    You know, we're not all Georgians. Simply because there is a very serious problem that we ought to be concerned about and we ought to be monitoring very carefully between Russia and Georgia does not, by any stretch of the imagination, mean that we ought to be becoming involved. And that clearly seems to be the direction in which both this administration and Senator McCain are going.

    CAVUTO: All right.

    So, Congressman, your view, the official Libertarian view — and not official, but sort of the accepted Libertarian view — is just butt out of these kind of foreign conflicts, right?

    BARR: Be aware of them. Be concerned. Try and mediate. There certainty are pressures that can be brought. And, you know, it's not that we ought to back away and say we have no interest whatsoever here. But I think it is foolhardy and, again, very simplistic to be jumping into these sorts of disputes. The one in particular here was, at least in the short term, precipitated very clearly by actions by the Georgian president.

    CAVUTO: Yes, that might be right, Congressman, but the response of the Russians was like an anvil on your head. They were obviously poised, ready and willing to see what was going to happen.

    BARR: But everybody knew that...

    CAVUTO: All right. But here's what I want...

    BARR: ... including the Georgian president, apparently.

    CAVUTO: Understood. And, by the way, he — he mentioned that on Friday.

    But let me ask you, is your position that even though you see signs of militaristic activity, as we would have seen with — with Hitler in the '30s, you just ignore it until you can't ignore it anymore? Or do you act preemptively, as essentially McCain seems to be advocating, that you don't ignore this; it's to your own peril if you do?

    BARR: I don't — I don't — I don't see that this is another Munich. And that's part of, I think, the...

    CAVUTO: How do you know?

    BARR: Well, because...

    CAVUTO: I mean, they just set up missiles. Now they have — if that's a guest's way of leaving, Congressman...

    (CROSSTALK)

    BARR: Well, they're not — they're not going — they're not going to leave completely. I think anybody would be simplistic if they believed that they're just going to pull out and, you know, everything is hunky-dory again.

    The Russians very clearly intend to maintain a great deal of influence in that area.

    But the people that ought to be...

    CAVUTO: But a President Barr would ignore it?

    BARR: No, I said, absolutely, I would not ignore it, being concerned about it, becoming involved through the Europeans to exert pressure on Russia.

    And, after all, it's the Europeans that really ought to be more concerned with this. And we ought to be going to the Europeans and saying, look, you know, NATO has outlived its usefulness. That was an organization, an entity that was put together 60 years ago, for heaven's sake, for an entirely different purpose.

    You all need to band together. You have a greater GDP than — than the United States of America, after all, the European nations. Yet, they're just sitting back and letting us do their heavy lifting for them.

    CAVUTO: President Barr would say no.

    By the way, getting to a President Barr involves getting candidate Barr in the debates. And you have a big task to get in the debates. You have to score 15 percent in polls to be there. You're at 6 percent, 7 percent right now. It doesn't look like it's going to happen.

    BARR: That's — that's not necessarily true. I mean, it is a tough road, no doubt about it. The cards are really stacked against any third party, even a legitimate one like the Libertarians.

    But many people in this country, as you know from studying these things very carefully over the years, don't really start to focus on the election, even on the candidates and what they're going to be doing, until after Labor Day.

    CAVUTO: The talk is, you're going to be pushing sort of like a blitzkrieg of ads to get your name out there, to get familiar to people, to build those numbers up. But getting to 15 percent is tough, right?

    BARR: It's tough, but it is doable.
