The West German govt. obviously thought Baader-Meinhof were serious and not just cosmetic radicals...They and the RAF may have spouted the then trendy Marxist-Leninist line, as most do about Globalization today
But in many ways the faction was much more like c19th Anarchists: direct overthrow of the state by force. Unlike contemporary terror groups who target civilians, B-M and RAF carried out bank raids, kidnapping, assassination of top politicians, bankers, police, military, judges, taking over embassies, targeting military bases etc. Most of the leaders were captured, some committed 'suicide', three of them Baader, Raspe, Enßlin were found dead in their cells. 2 had shot themselves the other hanged, rather mysterious as they had been in total solitary confinement for 2 years but had apparently hidden pistols and hanging aparatus...some said it was judicial murder. Other members repented but some not, in February of this year the German govt arrested a pensioner in her late 70s in a Berlin suburb on suspicion of her having been 'sympathetic' to the movement.
