From a political realpolitik point of view a civil war is an equalizer. Often the participants crave for it. Each party says that's what is needed to fix the country. They often speak of it as a picnic: you go have fun and come back home to sleep. Well, this picnic can last 100 years and only your grandchildren or great grandchildren will end it.
But it works. All modern civilizations we admire today have gone through it. In the 90s I told a conference on democracy that as far as I was concerned, the so called islands of peace - Kenya and Ivory Coast - are most likely to get embroiled in a civil war while the likes of Somalia emerge from theirs. There were incredulous murmurs. I'm proven right about Ivory Coast. Kenya has REFUSED to make fundamental changes to avoid civil war and is now helplessly hurtling down the precipice like a runaway train.
Kenya had a rare opportunity to avoid war. It had a vibrant economy with a booming private sector that dwarfed the state in employment.
Then Cronyism set in and it's only expanding. Private companies that were content to do their thing joined oligarchs to loot taxes and overburden citizens. Right now the tone deaf regime is busy singing how to further expand taxation to reach everyone. Businesses are being killed by KRA through corruption or just intimidation and harassment for shakedowns. The anger from owners of hardware's and wholesale shops is palpable.
The elite would hear nothing of ending the favoritism of ethnic oligarchs. Try telling them and they all out to drown you in propaganda and lies. But then few of them have lived in countries as they rush to war. The denial is replaced with shame as previously powerful people submit to former bus stop touts now war lords; as they die of treatable diseases because the hospital is on the "other side" but it's hardly functioning having been looted. Electricity cables are rolled up and sold. Upper middle class houses are dismantled brick by brick to be exported. You pay tolls to reach the market to buy food - if you have money. Most of the time it's you selling part of your NGO rations to buy medicine.
So I see the arrogance and shake my head.
All the civil wars in Africa were as a result of one or allied ethnic groups dominating others. The so called government became synonymous with one ethnic group. Their wealth and state wealth had no boundaries. This is the situation in Kenya. The same propaganda used to explain and justify it in Nigeria before Biafra, the lies of Siad Barre's clan or the claims of various actors in Chad from Felix Malloum to Habre - all merge in Kenya. When you've seen it all before it can be very lonely and you feel like John The Baptist or Noah (minus divinity).
So yes Kenya is more ready for war than any other country in the region.
Can it be avoided? No. The oligarchs have totally indoctrinated their followers. The current generation is incorrigibly damaged. The ethnic chauvinism and machismo is not repairable. When questioned about malignant electoral fraud, the answer is chest thumping and straight up insinuations suggesting the losers are stupid.
Anyway I think I've answered one of your questions.
