The rivalry is the heart of any sports. In terms of cricket, Pakistan India Cricket Rivalry is even bigger than Australia and England. When they compete with each other billions of people turn towards it. I don't think so anyone here talks like or talked about the likes of Basit Ali and Tanvir. As you already put things are at both sides of the border and you know its a huge population full of cricket lovers. I don't think so we should put focus towards Social Media, jokes, and opinions full of personal grudges where ex-cricketers have to settle their own scores. We have talked about in pure cricketing terminologies and opinions. Fans do not have personal grudges with any cricketer, they just want good cricket and on merit selection.
You know well that there are plenty of genuine cricket fans like yourself on both sides of the border who give a heck to the useless long talk shows and social media banter. In my opinion, the intense arguments and things happening over media because the arch-rivals are not getting the due cricket they deserve as well as the fans have been deprived of watching their favorite players competing each other with regular intervals in different venues. This is a Cricket loss itself more than anything else that both teams don't play against each other more often what they used to. When two rivals are competing in almost four years time, What would you expect then? Such shows, hype, talks, over excitement will definitely generate at both sides of the border. You can disagree for sure but that's how I see it and many other cricketing fans. When rivals of any sports play against each other, Entertainment and Excitement is the first thing that comes up and commercialism follows it rather than vice-versa. World Cricket needed India and Pakistan matches so I'd rather think they both teams should compete more often.
Moreover, there are some sane cricketing experts there as well, we can talk about Wasim Akram, Misbah-ul-Haq, Rashid Latif and even Akhtar (Little Blunt) who give pure cricketing reasons over performances most of the times. Similarly, good ex-cricketers with constructive views are well there in India as well.
The last thing, I'd not agree with a conclusion of some ex-cricketers that India is at par with Pakistan and there is a huge difference. For sure, the Indian team is more professional, having a better captain and consistent team balance at present. Both teams need to compete more with each other to judge the difference rather than comparing the two sides in a one-off match after 2 to 3 years gap.
Coming to overall World Cup, I think on paper four teams are cruising through to semis, England, Australia, India, and Newzeland with one-off upset from Bangladesh can turn things around. Most people are seeing England as hot favorite to win this World Cup but I think England bowling line isn't that good against quality batsmen and batting. I think all these four teams equal contenders for the Cup
