Wrong anology in regards to comparison of Kikuyus Merus Akambas with Russians Ukrainians and BelaRussians.
Russians , Ukrainians and Belarussians are one people originating from Kievan Rus(current Kyiv). They speak same language same genes same DNA. If you want to compare them then you can do so by comparing them as Kikuyus of Kiambu , Muranga,. Nyeri .
The Emperor of Kiev having conquered land distributed it to his children which eventually became the Russian Empire cities currently in Belarus, Ukraine and Moscow.(Same as movement of Kikuyus to Kiambu Nyeri ,Nakuru ,Lamu ,Laikipia Etc.)
If you want to mirror Kamba ,Meru to Eastern Europe then its Slavs Languages like Russian , Polish , Czechlovakish and Yugoslavish(Serbian, Montengro,Macedonia,Bosnia etc)
Americans want Ukrainians to form an identity same as Kiambu want to distinguish itself from Muranga and Nyeri but in the long run it wont succeed . They are one people not even one family.
There was nothing like Ukraine before world war 1. Lenin and Bolsheviks decided to set a land from New Russia(Lugansk/Donestsk all land left of River Dnepr formerly known as Ekaterina ) and name it Ukrain(plains) then added captured Polish lands (lviv, volodya) after world war 2 with Polish population which has brought up the current mess.
A meru can undersatnd Kyuk but a kyuk cant understand Meru same with Kamba . Compliments with Polish , Serbs can understand Russian but a Russian cant understand Polish. Russian and Ukraine diffence is the H/G and I/U. The languange is the same and thwy understand each other.
Kambas Kikuyu Meru are all one family just like Russians , Ukrainians and Belarusians.
But Kambas hate other siblings very much,I would understand why they have beef with Kikuyu for taking their land in thika all way to kilimambogo but Merus have never done anything to them.
Kambas are self harming and have crab mentality we need uniting but that wouldn't happen anytime soon
