"Gaza pales compared with Yarmouk, where Syrian soldiers and ISIS decapitators inflicted unspeakable horrors on Palestinian refugees – to no outcry from the Left. Israel was not involved in this catastrophe. If it had been, her critics would have gone ballistic."

"Chaos now envelops the larger Middle East, with no end in sight. A peace agreement between Israel and the Palestinians is more remote, more elusive, than ever before.

The radical left is hardly alone in failing to foresee the Arab Spring and its horrendous consequences. But it is accountable for providing vacuous and dishonest cheerleading when the Palestinians needed wise and honest counsel. Now, with the broader Middle East in turmoil, it might be too late."

"For nearly fifty years, the anti-Israel left has been committing crimes not just against Israel but against the Palestinians – and the entire peace process."
