Tanzania attempted to oust Mobutu since the 1960s. Che Guevara wasn't in Tanzania for climbing Mount Kilimanjaro. He went to Congo with great help from Russia, Cuba and Tanzania and the prime motive was "regime change" to get rid of a puppet regime. He called off the mission due to what he counted in his book, Congo Diary; "Laurent Kabila (then age 26) not the man of the hour"
Your so called "UN owned website" attests to the same facts that I earlier stated in may previous posts: such could have never happened without the knowledge and approval of Tanzania's state security organs.
I quote, "He was introduced to me by a Tanzanian Intelligence officer that I had known by name of James Nzagi." Why would Tanzania do that without having had a vested interest in that project?
"I heard of Mr. Kabila, having some bases in the eastern mountains of Congo" Why would any country play a host to such a person without sharing identical ideologies?
Did Tanzania try to oust Mobutu, YES. However small, did Tanzania play a role in the latter project, ABSOLUTELY.
What are we arguing here?
Reason why I said, with due respect, CASE CLOSED. You win, I lost.
