The honest truth is that Raila, like most politicians, used his influence to breach the peace, and through that forced every successive government to strike a deal with him. The only difference between a Raila and say a Kalonzo is the level of influence.
Raila had the audacity to claim the elections was stolen in 2022. He kicked off the chaos by leading protests on the price of unga. When that was not having the desired effect, a "whistleblower" emerged claiming that Raila actually had 8 million votes, and thus came the second round of violent protests which led to the bipartisan talks.
Then the genz protests came and Raila took full advantage with his kibera goons, which he promptly withdrew after his handshake with Ruto.
Raila was not a statesman. He was a virus that tested the immune system of the nation, and inadvertently the nation grew stronger as a result of it. Sorry to his family but Kenya is better off.
