One leftist Brit decides that the left-wing anti-Israel drumbeat is unwarranted, and her former allies vigorously protest. Read Lorna Fitzsimons' succinct explanation of her support for Israel and then scroll down to the comments her essay elicits. Many on the left seem to believe that if only Israel would stop defending itself against the Palestinians peace would be at hand.
It would, of course, but only because Israel as a nation, and Jews as inhabitants of the Middle East, would cease to exist. This would certainly make Arab Muslims, and perhaps much of the European left, happy as clams, but it's hardly an acceptable way to resolve the problem.
Until the Arab world reconciles itself to the fact that Israel is in the Middle East to stay, and that they have a right to exist, there will be no peace in that region. Every time the Arabs feel strong enough they will provoke new wars and conflicts with Israel and every time Israelis defend themselves they will incur condemnation from those parts of the globe that wish to see them gone.
