In last 75 years these countries never learn from their mistakes and still going on the way of conflict which is surely going to hurt both countries even right now many are feeling India is big and have right to do things like this but surely in long term they can also face consequences of these in long run I don't want to go in other topics like terrorist and politics but still they need to do some soft policies for the better future because if they will go like this then surely things could be worst for all.
Not sure about a conflict, BCCI rejecting the offer to play the Asian cup in Pakistan due to security issues and other teams started visiting them recently after a lengthy halt and the break was mainly due to security reasons and when India tours Pakistan may be the stakes are higher considering what happened to Sri Lanka.
As for me these conflicts are political and whenever India and Pakistan tend to amend their issues in the past there would be a terrorist attack and it was a recurring theme for more than 30 years and if PCB thinks that it is not safe for them to play the next ODI World Cup they can make the decision on not sending the team, it is fair for them to think on that aspect as well.
