General Richard Hawley[ed. Charley Hall has informed me that this was not said by General Hawley. It was a parody email sent around.

When he was asked, "Does violence only lead to more violence?", this is what he had to say.
This one is so stupid you usually have to be the president of an Ivy League university to say it. Here's the truth, which you know in your heads and hearts already: Ineffective, unfocused violence leads to more violence. Limp, panicky, half-measures lead to more violence.

Not "on trial," not "reeducated, "not "nurtured back into the bosom of love." Dead. D-E-Well, you get the idea.
If only Israel understood this.
