A guide to Israeli settlements - How and when did they start, why are they spreading, what are the concerns and should anything be done about them?

In Cairo this month, President Obama urged Israel to stop settlement construction in the occupied territories. "The United States does not accept the legitimacy of continued Israeli settlements," he said. Israeli Prime Minister Benjamin Netanyahu, in his own policy speech soon after, ardently defended the communities and the people who live in them. "The settlers are neither the enemies of the people nor the enemies of peace. Rather, they are an integral part of our people."

So what's all the fuss? We present a guide for the perplexed.

George Tiller: Healthcare Provider

Rare in the news coverage of the murder of Dr. George Tiller were the voices of physicians who referred patients to him. That's because, in the media, abortion features as an "issue," a battlefront in the culture wars, and only secondarily, if at all, as a medical procedure. The letter below, written by a physician in response to my comment in The Nation on the murder, is a rare exception, shedding light on Dr. Tiller's role as a healthcare provider. Many thanks to Dr. Laurence Burd, its author, for writing it.

Nor would they rush to congratulate longtime nemesis Mahmoud Ahmadinejad, the leader of a regional rival with nuclear ambitions.
