A real politician and a true fighter will always be there for Singapore, no matter what set-backs/mistakes happened before, he would stay behind and try to defend his job, his ministry, for the sake of serving the people who voted him in, and the president to approved his position.
But Lui Tuck Yew has choosen to be that man without conviction, without vision, without that fire in the belly, and is NOT PREPARED stay for the long haul to fight for a better tomorrow for Singaporeans.
This is my honest opinion.
A true servant will serve until the master tells him to retire.
Tuck Yew is a QUITTER.
(Just incase u are reading this Mr Lui, take back ur resignation letter, stay on ur job, and fight on like an Admiral that u were trained to be.)
