Rather then conducting such tests Pakistan must focus on how they will bring international cricket back on there soils. Such tests wont bring cricket back there. PCB is helpless on recent CZN and ECB tour cancellation. Its wake up call for small boards to voice for there rights otherwise whales will continue to dominate cricket and ICC.
Yes, there is no point to be emotional about this incident. If England and New Zealand have refused to play in Pakistan, it not the end of the world for them. I think they should try to invite some weaker teams in their country to play cricket and once the series are completed safely, it will give a positive message to the ICC.
Pakistan has already invited and played safely against RSA, SL, Bangladesh and Zimbabwe. It was time for other team to visit Pakistan but they refused. AFAIK, security was not the prime reason rather they were political decision. Either way its bad for PCB and bad for the game.
I am also saying the same thing but they should so some action like inviting more teams to their country or if ICC, don't allow this, then conduct more domestic tournaments and invite international players. I remember they started KPL this year along with PSL.
Only claiming that due to political reason no teams want to come here, why not find ways to improve the situation.
