CHRIS WALLACE: George, what's your sense of how far Putin and the Russians are willing to go in Ukraine, and what, if anything, can President Obama and the West do about it? GEORGE WILL: I think he will go as far as he needs to go to preserve Ukraine as a sphere of influence, if not actually an integrated part of his country because it's the key

"I don’t know what decade this guy’s living in,” Chris Matthews said in a March 28, 2012 episode of his MSNBC show, "Hardball." "It sounds like, if not ’72, ’52 even. It’s not Stalin over there, it’s not Khrushchev, it’s not Brezhnev. It’s Medvedev."

JOHN KING: If you're the Democrats, I know it's only March, but you have to look at those numbers and think, "we're about to get thumped."

REP. CHRIS VAN HOLLEN: If I can just say a quick word on the Ukraine, in response to the earlier section. We’re 48 hours from an international crisis, I would hope Americans would focus on condemning the actions of Putin rather than in a knee-jerk way, again, criticizing the president of the United States. Let's stand together on this. (Van H

SECRETARY OF STATE JOHN KERRY: It's an incredible act of aggression. It is really a stunning, willful choice by President Putin to invade another country. Russia is in violation of the sovereignty of Ukraine. Russia is in violation of its international obligations. Russia is in violation of its obligations under the U.N. charter, under the Helsinki

STEPHANOPOULOS: But do you have any indication at all that President Putin is taking heed of what President Obama is saying? KERRY: Well, they just had the conversation yesterday, and the president invited him to engage with the government. I understand there may have been one phone call. We're going to continue to engage diplomatically. This is

DAVID GREGORY: Before I get to my final question on Israel with a big meeting with Benjamin Netanyahu, the prime minister, coming to meet with President Obama, Marco Rubio is on this program in just a few minutes saying it's time for the administration to publicly acknowledge that the reset with Russia is dead. Do you acknowledge that? SECRETARY

DAVID GREGORY: 40 years ago, we weren't talking about legalizing marijuana in states either. Is that a good or a bad idea for California? GOV. JERRY BROWN (D-CA): Well, we have medical marijuana, which gets very close to what they have in Colorado and Washington. I'd really like those two states to show us how it's going to work. The problem wit

CHRIS WALLACE: Let's sort of talk big picture. How do you think President Obama has been handling relations with Russia versus how Vladimir Putin has been handling relations with the United States? HOUSE INTELLIGENCE COMMITTEE CHAIRMAN MIKE ROGERS (R-MI): Well, I think Putin is playing chess, and I think we're playing marbles. And I don't think

MARCO RUBIO: We know that the Russians have bascially violated every major treaty they have ever entered into. We see how they have bascially lied. Let's call it what it is: they are lying and this government is a government of liars, the Russian government.

GEORGE STEPHANOPOULOS: We are joined now by Secretary of State John Kerry. Mr. Secretary, thanks for joining us this morning. We've got these reports now, Russian forces surrounding Ukrainian military bases in the Crimea. Ukraine's prime minister says, "We are on the brink of disaster." Is he right? SECRETARY OF STATE JOHN KERRY: Well, we hope n

CHUCK HAGEL: This could be a very dangerous situation if this continues in a very provocative way. We have many options, like any nations do. We're trying to deal with the diplomatic focus. That's the appropriate responsible approach and that's what we're going to continue.

Former U.S. Ambassador to Ukraine William Taylor explains Ukraine's history with Russia and suggests that in order to be effective the U.S. and the international community must treat Putin's Russia like an "outlaw state, as we did with South Africa and Iran."

JOHN BOLTON: If you look at the White House read out, which I encourage everybody to read and try and pierce through the gobbledegook, Obama said Russia was "violating international law." That's just about the morse serious thing in the world to Barack Obama and its probably on a long list of priorities for Putin, something pretty close to the bot
