"A man who flies to Iran and murders Iranians with firearms is at least engaging in the war in a way that he will have to grapple with existentially for the rest of his life."

A man who flies to Iraq and murders American with bomb is at least engaging in the war in a way that he will have to grapple with existentially for the rest of his life.

I guess that makes it even then, the American contractor he killed just prior to his death,and himself are both now out of the grappling stages of their lives.
