I am struck by the willful ignorance too, the willful ignorance of MJ Rosenberg. Here's the key sentence:
"The Palestinians accepted Israel's right to security in 1988 & have never gone back one it. "What Palestinians are you talking about, Mr. Rosenberg?? The ones who voted for Hamas, or the ones who voted for Fatah?! Which of those groups accept Israel's "right to security", to say nothing of Israel's very existence?
Accepting that when the Palestinians talk they mean what they say isn't "being afraid of your own shadow." It's called facing reality, something Mr. Rosenberg clearly has no experience with.
