جبهة التحرير الفلسطينية
Feltrinelli published the writings of figures such as Castro, Che and Ho Chi Minh, and a series of pamphlets on the unfolding insurgencies and wars in Southeast Asia and the Middle East. He was a close friend of the student leader Rudi Dutschke, whom he invited to convalesce in Italy after Dutschke was seriously wounded by an assassination attempt. Feltrinelli gave financial support to the Palestine Liberation Front, among other causes.
