While supplanting a de facto life-long dictator might sound like a good idea to some, countries with weak institutions generally just fall into the hands of another power clique (or remain in the hands of the incumbent crony dynasty if it prevails).

From https://www.worldbank.org/en/country/chad/overview - "Chad ... is ranked last on the World Bank’s Human Capital Index.". This would indicate weak institutions which gives very little reason for optimism.
