"Ukrainians are struggling to generate the manpower that they need and to sustain their defensive efforts, and it's important that they get the weapons they need and the training that they need, but also they have to have the confidence that they can prevail," he said. "And any sort of messages that we might reduce our aid are quite damaging to them from a moral perspective."
McMaster said he's hopeful that Trump's picks, and the president-elect himself, will "begin to see the quite obvious connections between the war in Ukraine and this axis of aggressors that are doing everything they can to tear down the existing international order." He cited the North Korean soldiers fighting on European soil in the first major war in Europe since World War II, the efforts China is taking to "sustain Russia's war-making machine," and the drones and missiles Iran has provided as part of the broader picture.
"So I think what's happened is so many people have taken such a myopic view of Ukraine, and they've misunderstood Putin's intentions and how consequential the war is to our interests across the world," McMaster said.
On Trump's selections for top national security and defense posts, McMaster stressed the importance of the Senate's advice and consent role in making sure "the best people are in those positions."
McMaster outlined that based on his experience, Trump listens to advice and learns from those around him. And he argued that the nominees for director of national intelligence and defense secretary should be asked key questions like how they will "reconcile peace through strength," and what they think "motivates, drives and constrains" Russian President Vladimir Putin.
