The decision-makers of PCB, they have tried. They organized and prepared a high-profile ICC security delegates tour, everything was A-to-Z PCB. I would say they did push until they couldn't push longer, and after that, it was all ICC-show. The decision-makers however did push to have a tri-series tournament involving South Africa on their home turf which was also rejected and they had a valid reason to do that, so it is basically no cricket, let alone competitive cricket. This year alone, Pakistan has been more in the headlines on everything off-field, and less in-field.
I guess the decision makers can be blamed for not working their butts off and thus not providing enough opportunitues to Pakistan to play competitive cricket. These hasn't been much exciting on ICC FTP for Pakistan off late thanks to them.
