Therein lies the flaw. You expect your leaders to drop the the heavens and be all powerfull and right all the time.
I am sorry, but it does not work that way. You will have to suffer for years, till another political leader emerges who points out the follies of the other who is in power and his wrongdoings and takes away the votes. Then the next one comes up which does the same. Eventually all the politicians exhibit better leadership skills, as this is necessary for them to get elected. Slowly the people will also see which leader is actually delivering more. Its a two way street.
And Please, dont give the that most Pakistani's are not literate and thus cant understand whom to vote. Even an illiterate in the village knows whether to vote for a man who brings roads and electricity to him or for one who just delivers empty promises. Sure, it may take him 2 elections-10 years that is to get it right, but eventually he will learn and the ones after him as well.
You cant expect your first batch to do everything right. It is a continuous process. Slowly your country will start getting better politicians. The problem is you and i might add from reading PDF that others like you, expect instant results. The new government has just come to power, they are already shaky, since they have come to power the price of oil has gone mindblowingly high and because of that you have a record deficit. Does it mean that the new government has failed you?
Have you even allowed your leaders to mature? No. Your army deposes them at its whims and the sadest part is that many people think that its the Army's prerogative to do so. What you never realise is the immense problems you are facing now are the work of your army, which might be excellent as a defender of the nation, but not as a ruler, And the number of problems you will face as your nation enters the future.
Its a two way street, as the politicians mature, so do the populace become wiser.
Democracy grows and develops slowly as an institution , the problem is that your Army has never allowed it to grow, develop and take root.
