Najib say will not let nation down? He already has

Malaysia's worst Prime Minister Najib Razak proclaimed in his "Merdeka" speech that he will not let the nation down. How is that even possible? He already has let Malaysia down by his bad governance of the nation. He has spouted great flowery speeches but did the opposite of what he claims he want to do. He promised transparency but delivered the opposite. He promised to fight corruption but .... you can complete the rest yourself.
