Yes, he did liberate Zimbabwe from white minority rule but single handedly he laid waste to Zimbabwe.
For a while Zimbabwe did prosper under Mugabe. But as he settled into his new role as president of the country, the taste of power became too tempting to relinquish and he became conceited and ruthless.
He claimed Zimbabwe belonged to him, silenced the opposition and ruled the country with an iron fist for nearly 40 years.
From liberator to oppressor, president to dictator, he was respected and admired in Africa but despised in the west. He seized white-owned farms and turned Zimbabwe from the bread basket of Africa into a dust bowl.
