From Mike Allen's Playbook:

POOL REPORT: Susan Glasser, Peter Baker and Nurith Aizenman celebrated the publication of "Freedom's Battle: The Origin of Humanitarian Interventions," by their friend Gary J. Bass, a former reporter for The Economist who is now an associate professor of politics and international affairs at Princeton University.

HOW TO SELL BOOKS (FOR ACTUAL CASH MONEY) TO THE LIKES OF JANE MAYER, JULIET EILPERIN, ALAN COOPERMAN AND PETER CANELLOS: Susan and Peter's adorable 3 1/2 year-old, Theo, complete with blinking kicks, greeted each arrivee and demanded $25. He got it. He was very task-oriented, and we had trouble explaining to him that it was OK for folks to buy more than one. He was worried he would run out – a Washington book-party eventuality that only Theo could pull off.
Knopf's sneak: "Why do we sometimes let evil happen to others and sometimes rally to stop it? Whose lives matter to us? These are the key questions posed in this important and perceptive study of the largely forgotten nineteenth-century "atrocitarians"--some of the world's first human rights activists. Wildly romantic, eccentrically educated, and full of bizarre enthusiasms, they were also morally serious people on the vanguard of a new political consciousness. And their legacy has much to teach us about the human rights crises of today. Gary Bass shatters the myth that the history of humanitarian intervention began with Bill Clinton, or even Woodrow Wilson, and shows, instead, that there is a tangled international tradition, reaching back more than two hundred years, of confronting the suffering of innocent foreigners."
