Linked by who? PDF users and Iranian Mullah apologists?
US courts (several and years ago and more recently) all concluded that KSA had no connection to the 9/11. Other than 15 nationals (most of Yemeni origins and from Southern KSA) acting on their own in a third country.
Using that logic Pakistan should be guilty for numerous terrorist attacks in the West (7 July 2005 London Bombings) etc. and outside of it.
Let us just play with the thought for the sake of it and for having a bit of fun (after all this is PDF). KSA being behind 9/11 (most deadly attack on US soil in history - quite an achievement, even a bigger undisputed world superpower back in 2001), do you really, as in really, believe, that the US would not have acted against KSA (as in state ruled by the House of Saud) ages ago?
BTW, KSA was represented by the GCC in this vote (represented by 6 countries with equal votes) so it means nothing. Only Turkey voted for you (a meaningless vote) when everyone else voted against or refrained from voting. Maybe there is something about the accusations?
It's not like Pakistan did not choose to remain neutral (basically voted no) against even a symbolic participation in the Yemen war 3 years ago.
With that in mind, I don't see any reason for singling out KSA/GCC. Not like the benefits in the relationship are bigger for KSA/GCC either. The remittances that Pakistani nationals send back to Pakistan from the GCC is a way bigger number than KSA/GCC exports to Pakistan. Thus you are in the positive/plus in this relationship. It's actually the GCC that should be angry as Pakistan is bad (economic) business for the GCC leaders. Those are hard cold facts if we remove all feelings and non-existent brotherly ties when dealing with NATION STATES whose entire survival depends on doing whatever suits them the most.
Don't give me some useless comment about 1000 Pakistani soldiers/trainers (who would matter jackshit in a conflict, as proven in the Gulf War) being stationed in KSA, when KSA has cordial military ties with all world powers (literary) and most of the Arab world (500 million people, almost 3 Pakistan's) and an national military composed of almost 500.000 soldiers/national guards. Or some imaginary story of Pakistan founding KSA's army when KSA was already training with European powers (google the Saudi Arabian Air Force Wikipedia page and take a look at the photo that shows Saudi Arabian pilots training with Italian counterparts in the 1930's, almost 15-20 years PRIOR to the existence of Pakistan to mention 1 single example).
Like Pakistan is part of the "American Ummah" when it suits it, the "Chinese Ummah" when it suits it, the "British Ummah" or the "Iranian Ummah" when it suits it.
Probably other examples could be used.
Go ask the Afghans or Bangladeshis what they think about the "Pakistani Ummah" for instance. We can play the same game about you. Don't act holy and try to deal with the facts written in this post before barking.
