Nothing will happen.
1. Either ASIA CUP will be shifted to UAE or ASIA CUP wont be played ever again.
2. WORLD CUP 2023 will be played in INDIA only with or without PAK.
Rameez can be the next NAZAM SETHI if he wants to be, by damaging PCB by not participating in WORLD CUP and this time it will be the ICC that would make them suffer.
Its not VINOD RAI led COA thats running BCCI that it will listen to anyone. Amit Shah must have told his son JAYESH SHAH to make this announcement that India wont travel to PAK, else BCCI were open to tour PAK few days ago. Its clear that Indian Govt. has instructed BCCI. Sports minister Anurag Thakur is a part of Govt. and he knows Govt.'s stance regarding this and said the same.
