Angolan Civil War 

Hello: having worked on Angola for more than four decades, I have over the last two years or so tried to improve articles on Angola in WP (several languages). I was thus delighted to see your recent work on the en:WP article on the Angolan Civil War, which is a period I have somewhat neglected with regard to the military side. I wonder whether we can agree on the following points:
 The civil war in Angola ran from 1975 to 2002. The war for independence stopped effectively in April 1974, although a formal peace agreement was signed in January 1975 only. What I call the "decolonization conflict" is the fight between the nationalist movements & allies from April 1974 to November 1975 (independence). This conflict becomes a civil war after independence. Civil war can be divided in two periods: until 1991 (Cuban and South African military involvement) and 1991-2002 (external support only). I think this periodization is important, because it permits to specify the participation of other countries.
 There was direct participation of Cuba and SA in the fighting in 1974/75 as well as in 1975-1991. 
 I have never heard of the involvement of French & Morroccan troops: what are your sources? 
 The support of the Soviet Union consisted of air transport for Cuban troops, furnishing military equipment, and a few advisors, mostly in 1974/75, less in 1975-1991.
 Zaire supported the FNLA (logistics, equipment) and (small) contingents of troops, mainly in 1974/75, less so in 1975-1991 (when, as far as I know, the FNLA ceased it military activity as early as 1976/77)
 The US gave UNITA logistical, material and diplomatic support 1975-1991.
 China gave the FNLA some (unspecified) support in the early 1960s, and shifted this support (which then included military training in China for come cadres) to UNITA after 1966. This is uncontested  see e.g. John Marcum's book.
 Algeria supported the MPLA 1961-1974, mainly by hosting a pivotal group of MPLA exile cadres. I don't know about any further support.
 I don't have any sources on Libyan involvement.
 I am quite surprised at you mentioning the FNLC: what are the sources?
 Gabon and Côte d'Ivoire: I don't have sources, either.
 Mozambique: the FRELIMO regime has given "fraternal" moral and diplomatic support to the MPLA from the 1960s onwards, but as far as I know, there was no military involvement (so much the less as there was a civil war going on in Mozambique as well).

Do you think you could answer to all this, on this page? Thank you in advance
