In this age, I don't care how tactically or operationally brilliant you are, if you cannot create harmony - even vicious harmony - on the battlefield based on trust across service lines, across coalition and national lines, and across civilian/military lines, you need to go home, because your leadership is obsolete. We have got to have officers who can create harmony across all those lines.

No war is over until the enemy says it's over. We may think it over, we may declare it over, but in fact, the enemy gets a vote.

Treachery has existed as long as there's been warfare, and there's always been a few people that you couldn't trust.

You can overcome wrong technology. Your people have the initiative, they see the problem, no big deal ... you can't overcome bad culture. You've gotta change whoever is in charge.

Find the enemy that wants to end this experiment (in American democracy) and kill every one of them until they're so sick of the killing that they leave us and our freedoms intact.

PowerPoint makes us stupid.

The United States has been essentially engaged in an ongoing war that most people date from 2001. That war has taken us to Afghanistan, to Iraq, in a lesser way to other countries - Libya, Somalia, Yemen.
