Every country has security issues to an extent.
If we offer them Presidential security and have so far succeeded in holding the series emphatically without any events, why would you hold that AGAINST Pakistan?
Name me a country which has NEVER had security issues ever?
It's a good idea sometimes to listen to people from other countries and judge why your POV vs their POV isn't aligned.
Simply put, Pakistan has tarnished its reputation globally (through several political events - not related to cricket). Pretty sure it's not as bad as the media portrays it to be and not much worst than the current Asian countries. When election time comes, all Asian countries are alike, battles from different parties take on the field, people get killed, etc. But it takes forever to build a reputation, only 1 event to tarnish it for a long-long time.
Unfortunately for Pak, you guys took the L the moment SL players got shot at, you may think it's been years, why does it matter, well it does matter. Because right there and then it proved that your security is a joke and it was for the world to see. Even teams like BD/SL hesitates to tour PAK, even though similar political tensions exist in their country too, however, their image is much better globally than PAK (I am leaving IND out of this discussion because IND V PAK is a different type of quarrel politically).
What cricketjoshila is trying to explain is clear to me, and many non-Pakistanis (and hopefully to Pakistanis too). For some reason, you guys don't see it the same way. I am not sure why?
His POV: If you need to provide Presidential Security - means your country isn't as safe as you may think it is. There might actually be danger around which could be life threatening and isn't safe without security.
Regular security, each country provides to other visiting teams because it is necessary to prevent fans from harassing players/crazy people trying to attempt something/etc. If Pak is able to start hosting teams without giving presidential security, it might start shifting the image of danger. That's how it works, unfortunately.
P.S Don't think I don't feel bad for you guys, I do like many others, you guys have a good team but have to deal with this nonsense, but this is the situation, and am just telling you how it is.
