As undersecretary of defense for policy, Colin Kahl is one of the Biden administration’s senior most policymakers, tasked with formulating and coordinating the White House’s national security strategy.
In an hour-long interview on FP Live, Kahl told FP’s Ravi Agrawal that the Pentagon is working “24/7” to understand the scope and scale of the recent leaks, and to make sure it never happens again.
On Ukraine, Kahl pushed back against criticisms that the Biden administration has slow-rolled aid to Ukraine. “We are all in,” he said, adding that “Russia has already lost, by every measure.”
On China, “the reality is that Beijing is not picking up the phone when we’re calling them,” said Kahl. And on Taiwan, he explained how the Pentagon thinks about deterrence: “It’s important that the Chinese leadership wakes up every single day and says ‘today is not the day’ to launch an invasion across the Taiwan Strait … or to engage in other aggression that could threaten the rules-based international order.”
