A question about succession and betrayal ...

My father's old friend Uncle Lam from Ipoh's Canning Garden just emailed me to ask sarcastically why didn't Tun Dr. Mahathir Mohamad groom one of his sons to be his political successor like some of the smart first-world politicians in our midst did so that the question of feeling betrayed by successor would not arise.

Well, I think it is best for the question to be answered by Tun or those who feel it is their duty to explore it from all dimensions, including European perspective.
