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.
One of the big takeaways from Iraq was that you have to not lose confidence in what you are doing. We were able to go to the edge of the abyss without losing hope.
The basic DNA we've got to implant in leaders now is adaptability: not to get wedded to the solution to a particular problem, because not only the problem but the solution changes day to day. Creating people who are hardwired for that is going to be our challenge for the future.
Mike Hall was my old friend and, more important, the finest soldier I'd ever known. After over 30 years of service and then 18 months at a good civilian job, a phone call had brought the retired command sergeant major back on active duty to become the senior enlisted adviser of all international forces in Afghanistan.
Trust is an amazing commodity. The Afghan people often talk to me about having to develop trust in America, because they believe that we deserted them in 1990 and 1991.
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.
I'm a believer in the Afghan people, so I support an increase in forces there.
When I arrived in the summer of 2009 to command the war in Afghanistan, I entered an effort that was failing. Many Afghans, some ISAF coalition members, and much of the American public had lost confidence in both the trajectory of the war and our ability to correct it.
What scares me about drone strikes is how they are perceived around the world. The resentment created by American use of unmanned strikes... is much greater than the average American appreciates. They are hated on a visceral level, even by people who've never seen one or seen the effects of one.
Industrial technologies that allowed for increased mechanization in 19th-century armed forces also spurred Frederick Winslow Taylor to develop his 'Scientific Management' doctrine in Philadelphia steel mills.
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.
There's an art to asking questions. Briefings are valuable but normally communicate primarily what the subordinate leader wants you to know, and often the picture they provide is incomplete.
President Obama had voiced strong support for the effort in Afghanistan during his campaign, pledging to add two brigades, which he did. But since the inauguration... the administration had signaled that the U.S. commitment needed careful assessment, and we needed to recalibrate the strategy and objectives.
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.
If every soldier is authorized to make one mistake, then we lose the war.
The military does very well taking average people and making them very good leaders.
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.
America needs a big idea that plays to its strength. It should look to national service.
America needs a restart. It has long devoted its energies to solving its many big problems - unequal opportunity, crumbling infrastructure, lagging education, inadequate training in a changing economy, and threats to peace around the world.
Political campaigns offer Americans an opportunity to adjust direction, reaffirm values, and recommit to the covenant that binds them together.
