Here's some related information on Kerry's relationship to the antiwar lobby during the Reagan administration. This is scanned in from S. Stephen Powell,
Covert Cadre: Inside the Institute for Policy Studies, introduction by David Horowitz, Ottawa, Illinois, Green Hill Publishers, Inc., 1987, pp. 18-22. The specific information about Kerry is on the last page, 22, but I've included the prior pages for context in case some crossreferencing might turn up more information about Kerry's relationship to the other individuals and groups mentioned, such as IPS, the Cambridge Institute, the Committee on National Security, the Arms Control Foreign Policy Caucus, etc. In the present context of the War on Terror, note esp. the reference to the Middle East Research and Information Project (MERIP) founded by the IPS' Joe Stork.
PS: I've never tried posting a scanned page before so I don't know how easy to read this will look. If it's hard to read and someone knows a way to make it easier, please ping me and I'll try to fix it up.
Hmmm, that doesn't look very readable on my browser. Let me try that again, one page at a time using the full-sized version. Here's the page with the specific info on Kerry first; note that this is actually the last page in the sequence:
Looks censored to me.
