1973: Operation Mop-Up
A series of attacks by members of Lyndon LaRouche's organization in 1973 and 1974.
"Prior to the start of their "Mop Up Campaign," - against the CPUSA, the
NCLC sent one of their black sociopath's to our office with a copy of Marx’s
"Poverty of Philosophy." His task was to "feel us out" and present an
ultimatum to us: join their group or get "mopped up." His intent was to try
and create his modality for a fascist paramilitary group on us. Finding this
proposition amazing but not amusing, we politely listened, examined and
studied the relevant passages presented by this psychopath - Zeke Boyd to be
exact, then asked if he were willing to bring some of his comrades to the
office or any meeting place of his desire for further study. Upon agreement we
proceeded to present a non-literary propaganda form to convince them it was
best they approached the CPUSA, or someone us less desperate. Apparently
LaRouche himself made a decision we "were not worth expending organizational
resources on." "

FBI (1975): LaRouche's illegal possession of a number of guns and ammunition. UAW (United Auto Workers) informant believes "they may do something drastic such as assassinate Vice President Rockefeller"...
In September 1977 this letter from the FBI acknowledges LaRouche has publicly "denounced the use of force and violence" for political purpose.
And the FBI's investigation on LaRouche being discontinued in September 1977 is confirmed by this letter of Clarence Kelly:
In October 1977 LaRouche says: "Rockefeller may come over to our side"...

E.I.R. cover (Sept. 26, 1986) showing damages of an April 6, 1986 terrorist attempt against LaRouche's French HQs (the Cheminade 's then "Parti Ouvrier Europeen" (European Labor Party), renamed "Fédération pour une Nouvelle Solidarité" (Federation for a New Solidarity), later replaced by "Solidarité et Progrès" (Solidarity and Progress)).
The attack was claimed by a group called "Black War", a little ultra-leftist group targetting anti-communist, extreme-right/fascist (like Le Pen's Front National), anti-Greenpeace and/or pro-Apartheid political organizations/figures. LaRouche fitted the bill.
