Transcript for As president, I'd end 'counter-productive and wasteful regime change wars': Gabbard

She joins us from Washington, D.C. I want to begin -- you've taken on the idea, you said running for president to end regime change wars. I wonder what you thought about that line from governor hickenlooper's speech, some Democrats are recoiling from past foreign policy mistakes by withgraug from global leadership rules? Does that apply to you? No, I doesn't. My focus has been coming from my experience. I enlisted in the army national Guard after the terrorist attack on 9/11. Deployed twice in the middle East. In congress, served for over six years on both the foreign affairs and the armed services committee and bring that experience to the forefront where as president I will end these counterproductive and these wasteful regime change wars. Work to end this this new cold war and recognize how wasteful and costly these are. And take those resources and spend them on the American people. Education, rebuilding our crumbling infrastructure. Protecting the environment. Many urgent needs here to address. We need to get our priorities straight. You resigned your DNC post back in 2016 because you thought Hillary Clinton had a hawkish interventionist foreign policy. Does that apply to Joe Biden? We'll see what vice president Biden's foreign policy is for this country. We may agree on some issues, disagree on others. The problem that I have seen is that across both Democrat and Republican administrations, and especially in this trump administration where right now, he is leading us down this dangerous path towards a war with Iran. He says he doesn't want it. He says he doesn't want it. But the actions of him and his administration, people like John Bolton and Mike Pompeo tell us a very different story. They are setting the stage for a war with Iran that would prove to be far more costly, far more devastating and dangerous than anything we have seen in Iraq war. A war I served in where I saw firsthand the high human cost of war. One of the actions they took this week is evacuating as you know our diplomatic posts in Iraq because they were concerned based on the intelligence that Iran may be looking to hit American targets -- We heard conflicting stories coming from the British commander who was the co-commander of the fight against ISIS and Al Qaeda there in Iraq and Syria, saying, he hadn't seen an escalation of tensions or threats coming from these shia militia serving in Iraq. I think what we're seeing unfortunately is what looks like a lot like people in the trump administration trying to create a pretext or an excuse to go to war against Iran, a war that would actually undermine our national security, cost us countless American lives, cost civilian lives across the region. And it would actually make us less safe by threatening terrorist groups like ISIS. You said we have to end our new cold war. You have taken a softer line on Vladimir Putin. I want to put up a headline from "The daily beast" this week, Tulsi gabbard's campaign is being boosted by Putin a apologists. In the past you met with Assad. You opposed the arrest of Julian assange. Do you believe that Vladimir Putin is a threat to U.S. National security? You know, it's unfortunate that you're citing that article, George, because it's a whole lot of fake news. What I'm focused on is, what's in the best interest of the American people. What's in the best interest of our national security. Keeping the American people safe. And what I pointing out consistently time and time again is that our continued wasteful regime change wars have been counterproductive to the interest of the American people and the approach that this administration has taken in essentially choosing conflict rather than seeing how we can cooperate and work out our differences with other countries in the world have been counterproductive. Many Democrats have been tougher on Vladimir Putin than president trump -- I think that the escalation of tensions that we have seen between the United States and nuclear-armed countries like Russia and China -- and you're right, it has come from this administration, it's also has come from Democrats and Republicans in congress, it's brought us to this very dangerous point where nuclear strategists point out, we're at a greater risk of nuclear war now than ever before any time before. We have to understand the consequences of that. We in Hawaii know all too well with the wake-up call that we had about a little over a year ago when we got a text alert, over a million cell phones across our state, saying a ballistic missile was incoming, seek shelter immediately, this is not a drill. This was terrifying for people all across our state. Because there was no shelter and even though that turned out to be a false alarm, it points to the very real threat we face if we continue to go down this path of new cold war, ever-escalating tensions and a nuclear arms race and this is what I seek to change -- to build a friendships that are based on cooperation rather than conflict. Deescalate these tensions. And recognize -- an examples like denuclearizing the Korean peninsula. We've got to be able to work with countries like Russia and China to be able to accomplish that objective in order to keep the American people safe. Joined now by another democratic candidate Seth Moulton from Massachusetts.
