WI have toured Pakistan previously and there is nothing strange in there new tour in Dec 2021. Aus tour announcement just before semi final is strange, they never visited Pakistan in 24 years and now planning to visit Pakistan in Mar 2022 and that too just before semi final. Aus should tour or cancel in advance, must not do stuff like NZ did.
Nonetheless its all positive news for PCB and cricket fans in Pakistan.
It's a natural things change even in Pakistan case it's taking some more time and have serious troubles, but this change will happen because we all know 220 Millions peoples living and having some good life with many benefits and troubles is not a joke. Teams like Australia, England and New Zealand have some better hold, so just because of this they have done to blackmail Third World countries.
Now after IPL BCCI factor is also having big impact on ICC, and they have never been Pakistan friendly just because of this they are facing troubles. One thing is sure no one can ignore Pakistan in long run even they have not good financial benefits India, Pakistan rivalry is just a hate from few peoples, so it's never going to end because of education and religion affairs.
