That won’t work. If Mugabe is removed there will simply be a power struggle between the various factions, maybe even as far as civil war, before someone else equally as corrupt and vicious emerges as the new leader.
Seems to be the Pan-African way... Thugism or Communism. Then when it all goes to sh•t... they blame it on white-colonialism. When a country rich in recources can't feed its people because of a corrupt, jackbooted thug... the first line of business is to eliminate the thug and the swine who back him.
Should the thug have sufficient numbers to set off a civil war... then so be it.
