I am surprised that none of you mentioned that the Cubans badly needed to use Atkinson Air force base in Guyana to move Troops and military equipments to Angola. In exchange for using the base the Cubans armed and trained the Guyana's Peoples Militia. A few fanatic black soldiers from the Guyana Defense Force joined Cuban troops to fight in Angola and were killed by the UNITA rebels headed by the brilliant Dr. Jona Savimbi. In 1975, I watched the commotion in GT as Cuban troops began landing at Atkinson. Shell Oil company stopped refueling all planes entering and leaving Guyana. Burnham would declared it "Crisis in Georgetown".
During this time the Liberator Party's influence began to grow in the country side as Gunraj Kumar angrily told PPP supporters that the PNC have used Cuban guns to ram down a Marxist/Lennist Constitution down our throats. This statement would be used years after the Castro's visit and the use of Guyana's territory by Cuba in 1975.
