30 years after the fall of Amin, causes of 1979 war revealed

Since the narrative on Ugandan history is overwhelmingly negative toward Amin, reports such as this in the Uganda Weekly News that point to aggression too by Tanzania have tended to be disregarded by Ugandans and the world media and intelligentsia.
Then on October 30, 1978, President Amin ordered the army to invade Tanzania to claim the Kagera province for Uganda.
This, as far as can be ascertained for now, is the correct sequence of the events leading up to the war.

It is particularly interesting to note Museveni’s reaction to the news of the large-scale Ugandan attack on Tanzania, on page 93 of Sowing The Mustard Seed.

“Never since Amin’s coup in 1971 had I felt so buoyant as I did on the day following the invasion. I knew that Amin was finished… I remember walking along State House Drive in Dar es Salaam, on my way to consult with Edward Sokoine, with a feeling of complete satisfaction about the future course of events,” Museveni wrote.

If Museveni’s FRONASA was operating from Kagera, and Amin was constantly complaining about the presence in Kagera of Ugandan guerrillas trying to provoke conflict between Uganda and Tanzania, and the Ugandan invasion appeared to play into Tanzania’s hands, much to the delight of Museveni as he writes in his memoirs, it remains for Museveni to shed further light on the provocations that led to the 1979 war.
