My very identity as a soldier came to an abrupt end. I'd been soldiering as long as I'd been shaving. Suddenly I'd been told I could no longer soldier, and it felt as though no one really cared if I ever shaved again.
If who you were was entirely based upon the position you were in or the headlines you got in the newspaper, or you had essentially subcontracted out your self-worth to the judgments of others, then you're going to be like tumbleweed. You're going to be blown.
You're going to find out who your friends are. Anything that happens in your life is one of those challenges. It may not be at the level of celebrity, but everybody's going to travel that road.
In every relationship, there are two perspectives to it.
I think every war certainly wears on national will and national patience, particularly a counterinsurgency.
Any war or conflict you enter where you are likely to lose more Americans and expend more treasure is something worthy of very detailed debate. There ought to be a lot of skepticism. There ought to be a lot of discussion.
Throughout my career, I have lived by the principles of personal honor and professional integrity.
The challenge that we faced with the arrival of the Obama administration is, they didn't really have time to build trust before they had to make big, difficult decisions.
I think with the beginning of any political administration, you have to build trust, and it takes time.
I go back and think of President Kennedy, who had a military service background, but he comes into the presidency, and he's faced with a decision on the Bay of Pigs, with the C.I.A. and the military giving him data, and it turns out very badly.
Anyone in a position of power is either corrupt or assumed to be corrupt, and the assumption of corruption is as bad as the reality of it.
If we are visiting Afghans, typically the Afghan governor, district or provincial governor, we see he doesn't wear body armor, and yet we're walking through his streets. I'm his guest. I think that that's important that I send a message that I trust him and I don't think I am more valuable than I think he is.
We could do good things in Afghanistan for the next 100 years and fail.
By nature, I tended to trust people and was typically open and transparent... But such transparency would go astray when others saw us out of context or when I gave trust to those few who were unworthy of it.
Soldiers fighting a daily battle under frightening conditions can feel their leaders are far removed from their reality. There's no magic cure for this challenge, and soothing words that aren't backed up by action encourage cynicism.
Over my career, I'd watched senior leader visits have unintended negative consequences. Typically, schedules were unrealistically overloaded and were modified during the visit to cancel parts of the plan.
I think my biggest achievement was being part of a team of outstanding, entrepreneurial military leaders and civilians who helped change the way in which America fights by transforming a global special operations task force - Task Force 714 - that I commanded.
How Americans restore trust may be an existential question for their country, then, but it's ultimately a practical one: What U.S. society needs to answer it in the coming years aren't lamentations but practical measures, especially among the emerging generations that will define America's future.
A year of service has the power to bring young people together from different races, ethnicities, incomes, faiths, and political backgrounds to work on pressing problems facing U.S. society today.
