"I think that's most important is that we are listening to the Ukrainians as this war changes. Russia, as you know, is now planning to mass its forces from the east and come in heavy that way, which changes what they need. They need our -- heavy artillery. They need long range rocket systems. They need anti-ship missiles of the kind that they were able to use on the Russian ship in the Black Sea, the Moskva, their flagship, just a couple of days ago. And that's what we and our allies are assembling and continuing to get into Ukraine as these Ukrainians fight so bravely for their freedom, but also for the principle of freedom and sovereignty for all of us.... What I would say is, as you -- as you made clear at the top of your story, the United States has provided more than $3 billion worth of weapons to Ukraine. Our allies have matched that. So, double that amount over the course of this year. We were also the first to warn that Russia would invade Ukraine, starting as far back as late October, November. I think even the Ukrainians couldn't imagine the horror of what is happening now. But I think it's a direct result, not only of their bravery and their courage and their skill on the battlefield, but the fact that we've been working with them and training them, as have other NATO allies, for some eight years that they are able to stand up to the onslaught of the Russian army."
