Joshua Nkomo, who helped found the ZIPRA marxist guerrilla group which shot down the plane, was later exiled (to London, of course) by Robert Mugabe and his Zimbabwe African National Union – Patriotic Front (ZANU–PF) faction.
When Mugabe took full control of Rhodesia/Zimbabwe, Mugabe also conducted a massacre of Nkomo’s Ndebele tribe political base, more than 40K killed.
So what goes around, comes around
Also, never trust a Marxist.
Because socialism ==> genocide.
