I think you are trying to prepare nail soup. Nothing has changed about Obama's policies. The understanding and perception may have changed but that change is in the beholder not Obama.
I noted that Pundit states that Obama or is it US used to interfere. Of course this was the case and led to decolonization. The idea behind US support for decolonization was to gain access to previously ring-fenced British monopolistic markets and raw materials.
Come the Cold War and everyone stuck to whatever he could grab. Kenya transited from a British citadel to American power in the 80s after Britain suffered serious economic problems leading to the fear that Somalia might invade.
From 1978 - 91 - The US exercised some amount of influence over Kenya. It started off as being simply persuasive, with state visits to the US by Moi and constant high level visits by Sec of state (various). The granting of access to Mombasa and other military locations for the US military comes to mind.
This ended when there arose the Sub Saharan Spring that saw Kaunda, Banda etc go. Pressure was brought to bear on Moi. Trouble started.
I doubt that the US has ever sought to impose any leader on Kenyans. They may have preferences but I doubt there has ever been any direct attempt.
The narrative that Obama wanted to impose Raila was long discredited and I have taken it as part of the Kenyan political propaganda.
Osama has wisened in engaging countries especially Negroes;
1. A dictator is infinitesimally less risky than a managed regime change
2. Confrontations are a luxury America can't afford now that Kung Fu is painting the world red
3. America has finite and stretched capabilities so babysitting the world is wearisome
