Transcript for 'This Week': Samantha Power on Ukraine
Thank you very much. Let's bring in the U.N. Ambassador Samantha power. We have heard that there will be consequences if the Russia doesn't stand down. There's no question that Russian agents are behind this. That's what the U.S. Believes? It has all of the telltales that we saw in crimea, it's professional, coordinated. Nothing grass roots about it. The forces are doing in each of the six or seven cities they have been active in exactly the same thing. So, certainly, it bears the telltale signs of Moscow's involvement. Could the United States do anything that could stop Russia at this point? George, already the sanctions that we put in place have brought the ruble to an all-time low in terms of its value. The Russian stock market has depreciated by 20%, investors are fleeing. The president has made clear, depending on Russian behavior, mining could be on the table. And there's a lot in between. So, I think we have seen that the sanctions can bite. And if actions continue, we'll see a ramping up of those sanctions. Those sanctions didn't stop Russia from going into crimea, do we believe that Vladimir Putin wants the eastern Ukraine? I think the actions that he's undertaking certainly give credence to that idea, but I will say in the conversations that we have had, keep insisting, that's not what we want. Empg that they're doing suggests the opposite. Will they have control over eastern Ukraine no matter what? I think there are elections coming up, the leadership in Ukraine have made very clear they're prepared to have a conversation about autonomy. Just at the very time that they're going to the region to talk, this kind of action takes place. It makes you think that a military solution -- If they continue, do the peace talks still go forward? Unclear. Let me ask you about another issue at the united nations right now. The United States isn't going to issue a Visa to the man Iran has chosen as their ambassador in the U.N. Very clearly, the United States shall not impose any impediments to transit to or from the headquarters members of officials for the united nations how will granting a Visa to this ambassador harm U.S. Security? We take our host country obligations very serious. Part of our obligation is to review these oply cases. We have made it clear to Iran that this nominee is not accept able to us and we think the best way to resolve this issue is to pull it back and put someone else forward. Again, nothing in this quite public confrontation so far has had any impact on that. They're not going to pull the ambassador back, this ambassador served in Italy, the european union. So far, we had talks just last week, we'll have more high-level talks. We haven't seen this issue influence those talks in any way. And the urgency of that issue is plain to everyone. So, we would expect that Iran's own interests in getting out from under economic sanctions, which it says it wants, our interest certainly that Iran doesn't possess or develop any nuclear weapons. That will be paramount to us. Finally, some disturbing video coming out of Syria this week, right now, reports of another poison gas attack, the first since August, the rebels have put out the video. Syrian state television are claiming that the rebels rebehind the attack, not the government. We're trying to run this down. So far it's unsubstantiated. If the government did this, after the president draws the red line, after they promised to turn over chemical weapons, will we have any options but to strike militarily? Well, I won't get ahead of the president. The president has made it very clear how alarming he found chemical weapons used. That's why we have been able to destroy and remove more than half of Syria's chemical weapons up to this point. But certainly, the point, what we have done so far is prevent further use. We'll have to look at our policy options. Okay, thank you, Samantha. But right now, we're going to move on to Boston, a city
