A lot of times, you're interacting with people for whom you're one of the very few veterans that they've met or had a lot of interactions with, and there's a temptation for you to feel like you can pontificate about what the experience was or what it meant, and that leads to a lot of nonsense.
The wars in Iraq and Afghanistan are as much every U.S. citizen's wars as they are the veterans' wars. If we don't assume that civilians have just as much ownership and the moral responsibilities that we have as a nation when we embark on something like that, then we're in a very bad situation.
