For God's sake, this man cannot remain in power.

In this battle, we need to be clear-eyed. This battle will not be won in days or months either. We need to steel ourselves for the long fight ahead.

The gravity of the threat is why the response of the West has been so swift and so powerful and so unified, unprecedented, and overwhelming.

For God's sake this man cannot remain in power.

My message to the people of Ukraine is the message I delivered today: We stand with you. Period.

There is simply no justification or provocation for Russia’s choice of war. It’s an example of one of the oldest of human impulses: using brute force and disinformation to satisfy a craving for absolute power and control.

Don’t even think about going on one single inch of NATO territory.

These international sanctions are sapping Russian strength, its ability to replenish its military, and its ability to project power. And it is Putin who is to blame, period.

We have a sacred obligation under Article 5 to defend each and every inch of NATO territory with the full force of our collective power.

What`s at stake is what`s -- what are your kids and grandkids going to look like in terms of their freedom?

The single most important thing that we can do on the outset is keep the democracies united in our opposition and our effort to curtail devastation that is occurring at the hands of a man who, quite frankly, I think is a war criminal and I…

We are in a new phase -- your generation. We`re at an inflection point. About every four or five generations, there comes along a change, a fundamental change take place. The world ain`t going to be the same -- not because of Ukraine, but…

For God's sake this man cannot remain in power.

What you`re engaged in is much more than just whether or not you can alleviate the pain and suffering of the people of Ukraine. We`re in a new phase -- your generation. We`re at an inflection point. About every four or five generations…

My objective is to demonstrate that democracies cannot function in the 21st century.

It would -- it would trigger a response in kind, whether or not you are asking if NATO would cross, we would make that decision at the time.

Both Russia and Ukraine have been the breadbasket of Europe in terms of wheat. We talked about urging all the European countries and everyone else to and trade restrictions on sending limitations on sending food abroad. And so we are in…

I did not say that, In fact, the sanctions would deter him. Sanctions never deter. You keep talking about that. Sanctions never deter. The maintenance of sanctions, the maintenance of sanctions, the increasing the pain. That`s what will…

He now sees, this war, in Ukraine, as an attack, not only on the people of Ukraine, but on the concept of democracy, as a governing philosophy.

Folks, I just came by to say thanks. Thank you. Thank you. Thank you. Thank you. And what you're always doing, you know. 1 percent of you represent the entire of the Americans, 99 percent of the rest of the country, including me, thank you…

This is part of the reason, why Americans have - why we've sort of come to understand that Putin may have taken this step, because he thought that we were not unified.

I don’t think you’ll find any European leader who thinks that I am not up to the job. The next election, I’d be very fortunate if I had that same man running against me.

If chemical weapons are used against defenseless civilians, they would cause absolutely catastrophic casualties, children, old people, you name it, and that we would enter the war on the part of Ukraine if this happened, that ought to be a…

Putin was banking on NATO being split. My early conversation with him in December and early January, it was clear to me he didn’t think we could sustain this cohesion. NATO has never, never been more united than it is today. Putin is…

The very thing that Putin has tried to do from the beginning, and I’ve been saying this since my days as Vice President of the United States, is to break up NATO.
