IMO we gotta move past IK and PTI.
Let's say his government wasn't ousted. Heck, let's say he got re-elected. Even in that scenario, all of the underlying problems plaguing Pakistan would've continued to exist. The rot would've lingered, only to flare up another (albeit later) day. But we would've gotten to this point regardless.
What we're doing now by constantly vocalizing for IK/PTI is that we're arguing for marginally better "would have been" scenarios. We need to expand our vision and now work for fundamental changes.
Ultimately, IK had to play by rules in a game that didn't benefit Pakistanis. The moment he apparently broke those rules, he got kicked out. So, instead of complaining about how the game went, we should focus on stopping that actual game. If IK can buckle the first time (to rule initially), he'll do it again and waste our time.
We have a web made up of generals, politicians, judges, and top bureaucrats (plus their layers of underlings) who've sucked Pakistan dry. They've run a system that will never let any real change take root. Like, they're so deeht they won't even listen to the IMF.
Now, we have to critically examine what it'll take to dismantle this web once and for all. Even if people hit the streets Arab Spring style, that in itself doesn't result in real change. Real change happens when the "energy" is linked to a vision and credible leadership to succeed the old guard at every level, be it military, judiciary, political, or bureaucracy. From the American Revolution to the French to the Prussians to the Soviets to Madinah had this structural changeover.
Unfortunately in Pakistan, we don't have a true opposing leadership that is both equipped and recognized to supplant the current establishment. Basically, we've got too many sides who want to talk about the problem and complain, but too few who are either willing or able to do anything.
