Nope. Weather Underground’s first event was the Days of Rage in 1969 while the Chicago 7 were on trial for their activities at the 1968 DNC convention.
Ayers bombed the Pentagon in 1972 and there were Weatherman and Black Panthers robbing banks together in the 80s to fund their activities.
Saying WU were a 60s thing was Obama’s lie.
Sure, but by that time, both groups had devolved and shrunk to the level of common criminals. By the mid seventies, they'd both failed in their revolutionary missions. By the eighties, they were a broken shell of their former selves.
I was a young adult at the time, and well remember the events of those days. Hell, the Panthers even tried to recruit me during my high school years.
