Defense secretary on Russian invasion of Ukraine: "This could create a tragedy"

• "You could see a significant amount of combat power move very quickly now to take Kyiv," he added.
• "If he deploys that kind of combat power, it will certainly create enormous casualties within a civilian population."
• "And so this could create a a tragedy, quite frankly, as in terms of refugee flow and displaced people," Austin added.

Of note: Austin told host Martha Raddatz that the possibility of invasion was "not a bluff" and that Russia had assembled the "kinds of things that you would need to conduct a successful invasion."
