We are going through a general idea Eric Holder by secretary Chuck Hagel. Here comes the president now. More are running please be sued. But a year ago. Secretary of defense Chuck Hagel was visiting our troops in the Republic of Korea. Thanking them for their service and answering their questions and they asked about the usual topics. But our national security. The future of our military. And then one soldier a sergeant from Ohio or Aston. What. Was the most pertinent question of the day which was what was your favorite college football team. To which chuck replied born and raised in Nebraska. I don't have a choice I am a strong. Cornhuskers fans. Now there was a time when and enlisted soldier. Might have been reluctant to aspect got a question of the sector defense. But Chuck Hagel has been no ordinary secretary of defense. The first enlisted combat veteran to serve in that position. He understands. Our men and women like few others because he stood where they stood. He's been in the dirt and he's been in the mark. And that's established a special bond. He sees himself in them. And they see themselves in him. And their safety. Their lives have always been at the center. Of trucks serve us. What I asked chuck to serve as secretary of defense were Amorim. A significant period of transition. The draw down in Afghanistan. The need. To prepare our forces for future missions. And tough fiscal choices to keep our military strong. And -- Over nearly two years truck has been an exemplary. Defense Secretary. Providing a steady hand as we modernize our strategy and budget. Meet long term threats while still responding to immediate challenges like Beisel. And people. Thanks to chuck our military is on a former putting it engaged in these missions and looking ahead to the future. No last month chuck came to me to discuss the final quarter of my presidency. And determine that. Having guided the department through this transition. It was an appropriate time for him. To complete his service. Let me just say the truck it is and has been a great friend of mine I've known him. Admired him entrusted to him for nearly a decade since I was a green behind the ears. Freshman senator. And we were both on the Senate Foreign Relations Committee. But there's one thing I know about shark it's that he does not make. This or any decision lightly. This decision does not come easily to him but I consider myself. Extraordinarily lucky to have had him by my side for 2 years and I am grateful. The chuck has agreed to stay on until I nominate a successor. And that successor is confirmed by the senate which means that he'll continue to got our troops at this challenging time. All have more opportunity to pay tribute trucks life of service in the days ahead. For now let me just say it that's. Chuck Hagel was devoted himself to our national security. And our men and women in uniform across more than six decades. He volunteered for Vietnam and stills carries the scars and shrapnel. From the battles that he fought. And the VA he fought to give our veterans especially as fellow Vietnam veterans the benefits they had or. As head of the US so he made sure America always honors our troops. As a senator who helped lead the fight for the for the post 9/11 GI bill which is topic so many of our newest veterans and their families realize their dreams of a college education. The secretary chuck has helped transition our military and bolster America's. Leadership around the world. During his tenure Afghan forces took the lead for security in Afghanistan. For forces have drawn down. Our combat mission there ends next month and will partner with Afghans to preserve the gains we have made it. The NATO alliance is as strong as it has ever been. And we have reassured our allies where there are increased presence in central and Eastern Europe. We've modernized our alliances may Asia Pacific. Updated our defense posture and recently agreed to improve communications between the US and Chinese military's. Chuck has been critical to all. These accomplishments. Meanwhile trucks and short that our military is ready for new missions. Today are men and women in uniform are taking the fight against Beisel. In Iraq and Syria and chuck help build an international coalition. To ensure that the world is meeting this threat together. Today our forces are helping support the civilian effort against Ebola in West Africa. A reminder of struck likes to say that America's military as the greatest force for good in the world. Finally in a very difficult budgetary and mark. Chuck has never lost sight of key priorities. You can the readiness of our force and Paul live our life of our troops and their family. He's launched new reforms to ensure that even as our military is leaner it remains the strongest on the world. And so our troops can continue to get the paid. Housing. The health care of the child care that they and their families need. Reforms that we need congress. To now support. The same time. After the tragedies that we've seen chuck has helped lead the effort to improve security that our military installations. And to stamp out the scourge of sexual assault from the ranks. The chuck I also want to thank you all personal. We come from different parties but in accepting this position you send a powerful message especially to folks in this city. For more comes to our national security and caring for our troops and their families we are all Americans first. When I nominate you for this position you said the you'd always give me your honest advice and informed council you have. When it's mattered most. Behind closed doors in the Oval Office you've always given his foot and for that I'll always secret. You know call when I was a nominee in 2008. And and I traveled. To Afghanistan. And Iraq. Chuck Hagel accompany me on that trip along with victory. And it's pretty rare. At a time when. Sometimes this done so politicized. To have a friend. Who. Was willing. To a company a nominee from another party because he understood that. Whoever Libyan rebels most important was. That we were unified when we confronted the challenges we see overseas and that's the kind of class and integrity of the capital's always represented. Not shut yourself that a life's only as good as the family having friends you surround yourself with him in that you are blessed. One Banco rule about. This themselves. And her daughter Fallon for the sacrifices that they've made as well. I know that was reluctant where'd she go bear the equally getting her husband and father back. And I'm sure of the cornhuskers were also happy that. Fan will be there true tomorrow more often. Today the United States of America can probably claim the strongest military the world has ever known. That's the result of the investments made over many decades. The blood and treasure and sacrifices of generations. If the results of the character. And wisdom of those who leave them as well.
