I can write a book on Issa's contributions in various fields he has undertaken. For now, I need to remind all movements that seek to liberate Africa of two of his contributions that are, perhaps, not so obvious: 1) I do not know of any other African revolutionary who, after the so-called collapse of socialism and communism, unwaveringly gave intellectual leadership in support of the revolutionary paradigms that imperialism, through its ideological, intellectual, economic, social, cultural and political engines, sought to bury with the rubble of the Berlin wall; 2) As a Tanzanian, East African and African, Issa has defended Mwalimu's great legacy courageously and consistently.
