I don't think banning Pakistan altogether from world cricket would solve this problem. Dissolving the PCB, setting up an interim cricket administration in Pakistan which would comprise of both Pakistani officials as well as members of the ICC, Anti-Corruption Unit and other relevant bodies, and a life-ban to all the players involved except probably Mohammad Aamer would be my sort of a solution. If we isolate them at such a time of crisis, Pakistan would probably descend to more anarchy instead of getting better, as there's an acute lack of competent and honest people there who can tackle a degradation of such massive proportion. All sections of the PCB are as fragile and toothless as they can be, and the government is no better.
