For ICC tournament one possibility seems manageable if any 3 subcontinent countries bids for joint hosting rights? for ex; Ban-SL-Pak ? then Pakistan can host few WC games.
Well.. why not?
IMO, it may be an excellent idea for PCB, SLCB and BCB to make a joint bid for the major ICC tournaments. BCCI is extremely powerful and they don't need to make a joint bid. But that is not the case with these countries (Bangladesh, Sri Lanka and Pakistan). In case they could bid successfully, then I would really like to have one or two matches being staged in Afghanistan and Nepal as well. That can give a huge boost to the popularity of cricket in these nations.
I am not sure which world are you living in. In 2011, The world cup in 2011 was hosted by Bangladesh, India & Sri Lanka and they eliminated Pakistan. Now in 2023, they will alone host the World Cup, the Indians and they do not care if 3 others nearby cricketing nations wont get any matches and participation in it. How selfish would that be
