It's not that there is a choice between reform and implosion, but some prefer implosion. It's that implosion will occur because the reform that people expected doesn't happen.
If you look at the Kenyan system since independence, there have been two major changes. The first came with getting rid of the Moi tyranny, and it was a painful and costly process in many ways. At that point, when Kibaki came to power, Kenyans were very optimistic that they were finally on the right path. But a few years later we had the PEV, a very nasty "event" that led to the second major change: the new constitution.
The PEV did not occur during Kenya's worst years (the Moi years). It occurred during a supposedly better "time". That should be considered carefully. The PEV wasn't just about the elections; there was a bubbling cauldron well before that. We are heading into a similar phase.
Consider some of your proposals:
On Parliament we need to find a way to reform committees put in place measures that will reduce corruption in this institution.
Senate needs to be scrapped and its resources moved to county assemblies.. I think right now Senate is superfluous to Parliament.
Can we really expect any of that to happen?
Strong Judiciary, civil service and Parliament should be able to check the excesses of this office. Uhuru is the first president who has tried to emasculate institutions but is having little success.
What is true is that he has been unable to do things in the crude, old ways. Otherwise he is doing "quite well" in a similar fashion:
* In the legislature, he has a majority, and it is led by idiots that he controls.
* The civil service is entirely under is control, so I don't see how it can play role in checking him.
* The police? His man. The military? His people. Take a look at who has replaced flower-girls to meet and see him off at the airport.
* EACC? A joke. Apart from doing very little, its leaders can be disposed of at will. (Who has replaced Mutemu and Keino? Who will replace them?)
As I see it, things might look good, but that's only because the new constitution has brought some improvements on what was a hopeless system. But looking good and being good are two different things. What we have is a house whose roof, windows, paint etc. have been refurbished, but the foundations are still rotting. And that rot is called
top-driven tribalism.
