Great link for additional info on the Weather Underground. See page 3 of the FBI FOIA (1a).
Home grown terrorists serving a foreign enemy were alive and murdering American citizens long before militant Islam attacked the World Trade Center.
Re: “murdering American citizens . . .
Actually they Ayers’s gang only murdered themselves with a bomb. Of course Ayers is unapologetic for bombing government facilities.
I suspect they would have killed anyone who hinted at opposition to their efforts to destroy America.
