You're wrong.
Museveni and Kagame - and west - are aligned.
Don't be lured by those media game.
I worked with CIA kind of guys during Moi era - there are long standing rules/allies/name it.
US will always depend on Museveni and Kagame - in fact they keep training them.
It not easy to build alliance - and they dont destroy it.
Just like during Moi era - the US will pretend to talk tough for public - while classified stuff is happening.
Ruto is aligned with Museveni/Kagame/US/UK on DRC - meaning dont fight M23 - manage them.
I doubt M23 will attack kenya neither with DRC army.
The only problem is reputational risk - where everyone see KDF as ineffective.
Massacre - can only happen in Somalia - DRC those guys are cowards. You should see couple of their videos.
Nobody except Congolese want a peaceful powerful DRC - all of them just want to manage the violence.
Pulling out KDF yes! That is the wisest move at the moment. As for the rest of your statement, I believe the west pushed wsr into sending kdf into that cesspit.
Should we continue in that trajectory, start preparing bodybags and coffins, for it will be a massacre of huge proportions.
