“the insecurity of Israel’s defenders” – yes, indeed. They’re on the defensive these days. I heard Noam Chomsky the other day, on Democracy Now, say that he used to have to have police protection from Zionists when he spoke on campuses. Not any more.
As for apologies: Apologizing for something you said that was true, or something you did that was right, is wrong! Maybe you can say, “I’m sorry you were offended by what I said, but it’s true – too bad you can’t endure the truth.”
