I have heard that there was a meeting between Weather Underground and Chinese officials where Dorhn was present. Don’t know who else was present. In his article on Weather Underground for Rolling Stone Magazine, David Horowitz is supposed to have written that the Chinese gave WU the advise that 20-40 million would need to be eliminated if a communist revolution was to be successful. They should know of which they speak. If WU thought that only 25 million would need to be killed it shows they were probably just wild eyed idealists.
Have you seen Yuri Bezmenov KGB speak ?
