Political situation between both countries take twist when big powers intervene. I don't think it will be dry period forever and we can't say when it will last. India likes to play with Pakistan in icc events only since they have better record against Pakistan there. Victory in last T20 WC was first ever win by Pakistan against India in WC.
India has a better record in ICC events against Pakistan. But Pakistan is coming on though. They have performed quite well against India in the recent ICC tournaments. And I don't think that any change in any political power is going to help the issue that they are not playing against each other. I think this is one debate that even the players have just accepted and moved on, we all should accept.

In fact there have been demands from some of the political parties in India that they should stop playing against Pakistan even during the ICC tournaments such as World Cup and Champions Trophy.
If India have actually done that I think they are just dumb, whoever said that must be really dumb to think that ICC is going to let something like that happen. I don't think something like this is going to happen but I also don't think that these teams are going to play against each other outside of ICC events.
In order to cool down the situation, indian players should be allowed to play in PSL and pakistani players should be allowed to play in IPL. This will not only make both the tornaments more entertaining but at the same time it will create a friendly enviroment between the two teams and also among the public. Who knows due to this the tension between the two countires eases and they can have series with each other.
I think that's a good solution and a different approach to a unique problem. And by doing so, both IPL and PSL are going to have a huge boost in viewership. But in reality, I don't think that is going to happen.
