Robert Mugabe arrested! Reestablishment of Rhodesia when?

On the evening of 14 November 2017, elements of the Zimbabwe National Army gathered around Harare, the capital of Zimbabwe, and seized control of the Zimbabwe Broadcasting Corporation and other areas of the city. The next day, they issued a statement saying that it was not a coup d'état and that President Robert Mugabe was safe, although the situation would only return to normal after they had dealt with the "criminals" around Mugabe responsible for the socio-economic problems of Zimbabwe.[1] Jacob Zuma, the President of South Africa, phoned Mugabe and confirmed that Mugabe was "fine", but under house arrest.[2]
The coup took place amid tensions in the ruling ZANU–PF party between former Vice President Emmerson Mnangagwa (who was backed by the army) and First Lady Grace Mugabe (who was backed by the younger G40 faction) over who would succeed the elderly President Mugabe. A week after Mnangagwa was fired and forced to flee the country, and a day before troops moved into Harare, army chief Constantino Chiwenga issued a statement that purges of senior ZANU-PF officials like Mnangagwa had to stop.[3]

Robert Mugabe is gone, so who comes next? They call him 'The Crocodile'
The man poised to replace Robert Mugabe as Zimbabwe's president is named Emmerson Mnangagwa, but he's known as "The Crocodile".
He served for decades as Mr Mugabe's enforcer — a role that earned him a reputation for being astute, ruthless and good at manipulating the various levers of power.
Among the people, he is more feared than popular, but he has friends within the military and security forces.
These are the recent major moments for 75-year-old Mr Mnangagwa:
• He served as Mr Mugabe's deputy from 2014 until about a month ago when the Zimbabwe leadership crisis kicked off
• At that point, Mr Mugabe fired him for showing "traits of disloyalty" (there was speculation first lady Grace Mugabe would be his replacement)...()
