Ok , but aren't you contradicting yourself here ? You listed all the help the Saudis provided us in the past , which is fine and a ground reality , but did they do it without expecting anything in return ? For starters , let us say " Nuclear umbrella " and training of their army ...
Yes , its quid pro quos , it depends on who gives us the better deal now ... With KSA signing defense agreements with a hostile neighbor of ours , we have all the right to protect our interests without any regards for the delusional " Ummah " concept here ... I will add " pro re nata " ( As the circumstances arise ) here ... We had a taste of it in the 80's and we are still regretting setting of the Madarsah producing the suicide bombers and fuelling chaos in the country ... I for one , do not care for Arab/Persian rivalry ...
I have no idea what purpose this "Nuclear Umbrella", that you talk of, has served for Saudis. The Saudis were never under threat from any nukes. The nuclear weapons built by Pakistan, were to counter the threat of India, and nothing else. Calling it an Islamic nuke or anything on that line is nothing more than engaging in useless wit.
And even if by any remote chance this "umbrella" were a real thing of some practical use, then out of KSA and Iran, only one country could be considered under it. The other is always under existential threat because of this very "umbrella".
As far as training of their army is concerned, look at the favors of Saudis that I listed... compare... and this training thing looks even cheaper than peanuts. During Iraq Kuwait war, they called in the Americans, and even if they had called in Pakistanis, it would still be almost nothing compared to their favors on Pakistan. Come on man, I am not a Pakistani and even I could list more significant favors on part of Pakistan - not that they would still be great enough.
If these were the starters, I wonder what you would offer for the main course.
That bold part is very interesting. The Madrassas were set up to offset the need for educational infrastructure - was it really such a bad thing?
The people were not bothered by lack of such funding, and the government was only too happy to not commit any funds... don't blame it on Saudis because diversion of funds away from education is happening even today.
They just supported you in whatever way you wanted, now that it didn't bring up the desired results, you are blaming them. After all, the education may be theirs, but the ones roaming around with bombs and guns are Pakistanis, right?
