That is only possible in non-democratic countries otherwise if was that easy - Raila would long be dead by now. Such fights will be political. Uhuru I mean the best is can do is take you to court and charge you for real or trump charges, you'll be out in a day after posting bail & send KRA on your business - which you also can challenge in court - and that is pretty much it.
DCI or Kenya Army cannot help you that much. Unless you went for extra-judicial actions like assassinations.
At end of day - this will be MAD - Jubilee party will collapse - Jubilee majority will also collapse in parliament - and Uhuru will have no option except co-opt Raila & Kalonzo into gov. Ruto will have to become opposing DPORK - and will try to gobble a coalition against the "handshake" - who will be frustrating gov they serve.
So the biggest winner in such a war are NASA - mostly Raila - whom Uhuru will need.
At end of the day - this will be another Kibaki 2.0 - Uhuru solid legacy will be thrown out of the window - and Raila will have the last laugh.
Both Uhuru and Ruto will most definitely be back at ICC in 2023 after a big war erupt in the valley.
Once you control the state, you don't need much to fight. It's like calling The KDF Chief of Staff and telling him you must be re-elected. He considers it an order and proceeds to deliver.
