Awoken by sirens wailing over large parts of central Israel last weekend, I pulled on whatever clothes I could find beside my bed and shuffled down to the bomb shelter in the basement. The missiles, launched from Yemen by the Iranian-backed Houthis, didn’t distinguish between ideologies or identities. More or less every Israeli in the strike zone – left-wing or right-wing, religious or secular, Jew, Arab, Christian, Muslim, or other – did the same.
