My observation of the SPF mirrors that of SMRT - everytime a new boss, be it comdr or director takes over, most would parachute their kakis. All these are the CMI type. Those who chose to lead w/o cronies surrounding them are the ones who succeed. I dont recall Leo Yip bringing in his kakis.
This trend originally started by Kuan Yew for his son Gay Loong mah. Gay Loong did not have CEC support, so mke him a BG and make a bunch of others like him generals, and send them all in to surround him in the cabinet and play yes man. SO, what is new?
