COSTELLO: And good morning. I'm Carol Costello. Thank you so much for joining me. An alarming new warning from outgoing Army Chief General Ray Odierno -- Russia, not ISIS, poses the most dangerous threat to the United States. Listen to what Odierno told reporters on Wednesday.</s>ODIERNO: I believe Russia is the most dangerous because of a couple things. First, they are more mature than some other of our potential adversaries. And I think they have some stated intents that concern me in terms of how the Cold War ended. And so for me, I'm concerned.</s>COSTELLO: Odierno also cited Russia's sophisticated operations in Ukraine where Russian-backed fighters are locked in a fierce battle with the Ukrainian military. Odierno isn't the first to sound the alarm when it comes to Russia. Last month, incoming chairman of the Joint Chiefs of Staff, General Joseph Dunford, voiced similar concerns to lawmakers on Capitol Hill. So, let's talk about this with CNN military analyst, retired Lieutenant General Mark Hertling. Good morning, General. Thanks for joining me. LT. GEN. MARK HERTLING</s>CNN MILITARY ANALYST: Good morning, Carol.</s>COSTELLO: Good morning. So, first off, do you agree with General Odierno?</s>HERTLING: Well, I certainly think General Odierno is correct in saying that Russia is a threat. I'm not sure I completely agree with him saying it's the most dangerous, but it's certainly a growing concern. We saw that up close and personal when I was commander in Europe.</s>COSTELLO: It seems he's saying that Russia is more of a threat than is. Is that what he's saying?</s>HERTLING: Well, I'm not sure I would interpret it that way.
