Vietnam, when it was a very divided country? REPRESEN TATIVE SETH MOULTON: You know, I think there are actually a lot of – a lot of parallels. And one of the lessons that we should learn is to – to do right by our veterans, if for no other reason we've got to work on coming together. And, you know, it's – it's difficult when it feels like we've got the divider in chief to quote one of his former officials, at the head of our government right now. But that doesn't mean that those of us in Congress, especially veterans, can't work together.

(voice over): Iowa Republican Zach Nunn spent 20 years as an Air Force intelligence officer as still served in the Air Force Reserve. North Carolina Democrat Don Davis also served in the Air Force and told us that his work as a mortuary officer at nearby Andrews Air Force Base makes Memorial Day especially important to him. After the wall was cleaned, we talked about their work together on Capitol Hill. MARGARET BRENNAN: Congress did give that boost of pay last year to the troops. Is it enough in this economy though? Is the country doing enough?

REPRESEN TATIVE DON DAVIS (D-NC): We know that families are still struggling to make ends meet. Taking care of the day to day, kids, putting gas in the tank. So, it's definitely, I'm sure, not enough. But we are moving, I believe, there with that (INAUDIBLE) in particular in the right direction, not only with pay, but looking at broader quality of life issues, housing, childcare that's available on our installations. MARGARET BRENNAN: America spends more than any other country on its defense. How is it possible we have this happening to our troops?

REPRESEN TATIVE ZACH NUNN, (R-IA): We've tried to work together on things that not only help veterans, leading a veteran's suicide bill, assistance to families in the military. I'm proud the bill that we just passed is going to be able to extent a 22 percent tax cut to military families. I'm proud that we got a child tax credit in there. I'm thrilled that we were able to get our bill in there that worked towards giving a family a tax credit for adoption. We've got two adopted kids. This goes a long ways to helping a middle American family, whether you're military or not, be successful going forward. Ay aunt, who had two little girls. These are the stories that I think it's so important that young people do have the opportunity to learn about. One, so we never enter this kind of a situation again where we send men and women off to fight and they come back home, not to a hero's welcome, but as a despised class. Peace through strength is a real deterrent. But also knowing that we have a military that when we commit to fight, we have to go in there knowing that we have a strategy, a plan, and that we're not going to be bringing people home injured, broken or shattered to a country not ready to receive them.

MARGARET BRENNAN: And we will be right back. (ANNOUNCEMENTS) MARGARET BRENNAN: That's it for us today. But on behalf of all of us here at FACE THE NATION, to our military, our veterans, and especially their families, thank you for your service. We are all in your debt. Until next week, for FACE THE NATION, I'm Margaret Brennan. (ANNOUNCEMENTS)
