This chapter shows that domestic acts of violence and sabotage by New Left and other radical groups increased in frequency in 1968 and 1969. Intelligence from numerous reliable sources purported to show their collaboration with Cuba, North Vietnam, and other foreign powers. The Soviets continued to play a smaller, subtler role in these operations, but in 1968, the Kremlin seemed to show greater interest compared with earlier years. Some intelligence pointed to limited, but important, connections, such as an SDS leader’s explosives training session in Canada led by Soviet officials.
