Unfortunately, team that is playing cricket and representing Pakistan is not Pakistani team, rather this team is a team consisting of players on basis of personal like and dislike, hence it is team of nepotism, and worse is that even amongst these privileged players, they have groups.
When one group plays politics on personal like and dislike at the expense of Pakistan then that group should not expect that others would not play similar politics against them at the expense of Pakistan (possible for even personal grudge against such group).
This is the reason team should be selected entirely on merit ... there should be point system representing performance in domestic cricket (test cricket should get included in point system too once a player gets selected on performance in domestic cricket) ... and selection should be automatic on basis of that point system (no selection on personal like and dislike). Further, if any player is found involved in politics than that player should be out of team, how good a player he may be.
Perhaps its the first time I agree with you :D
