Justin Vaïsse, "Was Irving Kristol a Neoconservative?" Foreign Policy, September 23, 2009.

Excerpt:

Although a few other neoconservatives followed Kristol’s realist line (Glazer and, to some extent, Jeane Kirkpatrick), for most of the others the idea of retrenching and playing a more modest international role disturbingly looked like the realpolitik that had led to détente and other distasteful policies. The vast majority of Scoop Jackson Democrats advocated a more assertive and interventionist posture and continued to favor at least a dose of democracy promotion (most notably Joshua Muravchik, Ben Wattenberg, Carl Gershman, Michael Ledeen, Elliott Abrams, Podhoretz, and others). Their legacy would prevail.
