Wonder if he would say the same about Nazis.
Sometimes the weapons need to be louder than the dialogue - because there can be no moral compromise with pure evil.
The "dialogue" is a smokescreen anyway. Maybe Spielberg should have done a movie about Saladin. His idea of "peace" was regrouping. He hates violence, but apparently Spielberg hates the hard decisions more. Nihilism is an easy way to avoid having an answer for problems.
