@PakFactor [just including you as you asked for]
Why should Pakistanis die for a monarchy which displays filthy and shallow way to express it's public life?! Why? I am not being ungrateful for the help the Saudis have time and again extended to Pakistan. I strongly believe they did that NOT because Pakistan can
protect them but because the Saudis really see Pakistan as an honest brother friend. But that friendship has its limits too, from both sides and that has reflected in the public policies of both countries. Let me try to explain that.
Pakistan had remained more or less neutral on numerous occasions--the Iran-Iraq war of the 1980s, to the first Gulf War, to the second Gulf War, the Syrian war, the Yemen war... All these wars had serious security implications for Saudi Arabia. Why did Pakistan do that? Because, for one thing, while the Saudis have been helpful to Pakistan, the Saudis could have done a LOT more; the Saudi royal family probably spends more on luxury lifestyle every year than the entire Pakistani yearly defense budget!! And maybe the reasons Saudis don't do more for Pakistan is because the Saudis know that Pakistan, beyond a token division or two of armed forces, simply cannot afford to 'protect' Saudi Arabia when Pakistan is facing a two-front war since 2001; and that war would become a THREE front war had Pakistan committed more to Saudi Arabia. This forum has a lot of defense experts. Ask them to 'game' a scenario where the United States makes some deals with one of the regional players to oust the House of Saud! See what Pakistan can do. And please don't bring up the Pakistani nukes--they will be decimated as soon as they are detected in a hostile posture toward American interests!
To re-affirm, there are not doubt brotherly ties between the two countries and a deep trust. But they are, in fact, TWO different countries and are, in fact, even less of 'natural' allies than America-Canada are, because of geographical and Pakistan's own security compulsions. Pakistani and Saudi planners have always known about the limits of the relations and about potential quid pro quo.
Pakistan should appreciate and help the Saudis who have helped Pakistan time and again, although they could have done a LOT MORE for Pakistan. Often the Saudis did it because of faith in Pakistan. In return, Pakistan cannot offer the Saudis what the Saudis might need for the Saudi security. Pakistan itself is just coming out of a decade+ horrible period of terrorism and still faces a 2-front war.
I am not one of those who raise the shallow slogans of 'Pakistan First'. Pakistan had always been first and Pakistan had to be first. Pakistan is not a country in the middle of nowhere. Since 1947, there had always been a specter of two front wars and except for between 1996-2001, when the Talibans ruled Afghanistan, Pakistan has been facing the threat of two front war since 1979. Lowering the guard or strategic over-reach is suicidal for Pakistan!
