Political parties and affiliations have divided people in this world more than racial, lingual and religious differences. If this is true for the world it is also true for Malaysia. The Muslims and the Malays in this country had never been been segregated or divided because of the different States they come from or the dialects they speak. It's the political parties they support or affliate themselves with which divide them and had caused unpleasant and even harmfull relationship.
UMNO and PAS must of course accept this fact although none should be blamed for it's the nature of political development in this country which led to that situation. It is the nature of politics to divide people into interest and pressure groups in order to gain support and compete for power to rule over the population. Polical parties are the instrument and the outcome of such division. It's as natural as the the different branding of the same consumer products to compete for customers in the open market.
Asking political parties to merge or enter into a coalition in order to reduce divisiveness among the people is like asking companies producing different product brands to sell their products under just one brand. It's like asking the companies themselves to merge their interests. It can be done, of course, but it isn't easy. This seems to be the dilemma facing the UMNO and PAS leadersip in response to the call to bring the Muslims and the Malays together again. Each has it's corporate image and interests to protect with its own team of affiliates to consult, even when the arguments for such a move are very pursuasive and convinving.
UMNO and PAS had experienced a coalition before and it didn't work for long. PAS was then standing on its own without other affiliates, official or otherwise. Now it's no longer so and that makes a coalition with UMNO more difficult. Even working together would be difficult because each is guided by a different beacon. The perplexing enigma is that the beacon is the same if it is Islam. Unless they have different versions of the religion, they shouldn't be going in different directions. If it is a matter of pursuing the same goals through different methods and strategies, then at some point they must still converge.
The question then is: where will that point be? Will it happen before GE13 or after?
