The political leader should realise that national entity is over all. I don't think replacing with Megawati or somebody else will solve the economic problem and disintegration of the nation. I have worked in Jakarta in 1994-95. During Suharto rule there was no political freedom but the economy and national unity were far better than now. If the person has no job or money, it is very easy to make that person a religious fanatic.
Corruption is at the root and no political party other than military rule can control it.
Worse, his mental coherence is also failing. His successor will need a fuller mandate and the full support from the Army. There is no credible leader in the wings and unfortunately no sense of national discipline. The difference between democracy, mob rule and anarchy has not yet been learnt here. I fear that much blood will have to be spilt before the problems can start to correct themselves.
