Mahathir is the true enemy of Rakyat. He destroyed all key civil society institutions, destroyed social institutions, jailed human right champions, jailed elected representatives of the people especially the opposition members of parliament, allowed fascism to permeate into his political party (UMNO).
In that process he had his own political party de-registered and opened a fake UMNO in which he had total and absolute control to the extent he rule unopposed and unchallenged without internal party elections for years.
On the commercial front he squandered billions on Putrajaya and Cyberjaya, two towns (that's what they are, not cities) that are not functional, effective and useful to the citizens.
When his poor financial management of the country collapsed under the 1997 financial contagion, he conveniently blamed the Jews. In his own country he called the Chinese people "Communists" in one of their own party conference -they kept quiet.
Now he is in a hurry to kill off Badawi politically so as to avoid a situation where Anwar may come to power and unravel Mahathir's sins. If only he can get Najib into power, he may be able to direct a "Operasi Lalang" II which may see Anwar going into ISA detention thus preventing him from being an effective threat to Mahathir.
Who and what can be done about this? Nobody and Nothing. All powers rest in the hands of the future PM who will replace Badawi.
Mahathir is returning to power, only this time via someone else. Anwar is going back to jail. The rakyat will continue to be "occupied" by these rapacious colonist.
