It is astonishing that Pakistan has survived its leadership so far. That might lead to a trapped feeling, and a reluctant surrender to @Kaptaan 's thesis, that there is an underlying centripetal force that has held what we now recognise in state form as Pakistan, and that this force has existed for millennia. This is not the place to dispute the thesis, but it is fair to acknowledge that in the absence of a meaningful leadership - individuals are not considered, @Nilgiri, even as I agree with you that some of these individuals are peerless in their way - there must be some factor keeping the country together; even more, keeping it a viable option at all times, and for the entire 73 years so far.
What this is, or these are, belongs IMHO to a separate discussion.
Oh I know, this is a deeper vein. We are the same people Joe, deep down. How wonderful yet poignant for me to read some of your messages to the Bangladeshis in PDF.
If "we" are able to survive our leaders, "they" will all survive theirs too.
More broadly it is human spirit from how we are nurtured and protected and developed by a family. This psyche is then transmitted in some fashion to local community, area and nation as we inherit it and born into.
But it doesn't eclipse or replace the underlying bonds of original ancestors that migrated to and settled all this land.
The particular regional+cultural flavour of resolve...the deeper solidarity and bonds we often sense.... I see this across the world in general, and this is why hope springs eternal for me past all the predicaments humanity faces.
I never quite felt the particular online variant of this as when django my buddy at PDF started a long convo with me (a number of times) about BR Chopra Mahabharat and how he was absolutely enthralled by it heh....and just moments later he would take part in a big fight with some other Indians on the forum.
Brother wars and strife are not new to us or our progenitors....and neither is the ethos of firmly picking your side in a downstream strife when push comes to shove and give the best you can to your righteous cause as you see it. I personally sense it is a deep shared solidarity (conscious or subconscious)....even when we clash and fight. That is why I do not begrudge those brothers on the battlefield....in whatever sense...I begrudge the larger reasons and maybe inevitable cycles of bringing brothers to the battlefield.
In recent times I see the latter mostly manifesting as a political "class" of great hubris, ego and little connection to reality down here...they are not among us....yet steer so many of us. None of us down here deserve that....but it takes an awful lot inside to desert your brothers in what you see as their continuing time of need and resolve given all you invested in them and they invested in you....and pick some much higher path. Thus I do not judge most too harshly....these are sacred bonds. Rather curse those, that sit well away from it, have no honour or guts... and exploit this for foul gain.
