No matter how good a gloss they place over things, the current PAPzi government has lost its moral bearings. Things may not fall apart now, or tomorrow, but if they are not checked, they will go the way of the Duvaliers in Haiti, Marco in the Philippines and numerous Chinese dynasties that came before.
Worst of all, we go down with them.
So, the unlikely possibility of disparate now opposition parties may be inconvenient, but in the middle term, that is more stable for Singapore.
