I agree with you on this.
But when Pakistan team was united during babar time everyone started complaining Bhai chara should not be appreciated in this team. Tbh team was not performing upto the mark but their was unity, players were not fighting with each other, only two person created that mess and those were unsurprisingly our two legends imad and Aamir. So yes what I have learnt is team can gel and be united, problem is Pakistani fans we ourselves don't know what do we want from the team. If something is working we try to break it. If someone is not performing for a long time, His mantra is simple let him be away from a team for a year and fans will start calling his name.
Every team has their own strength and their own weakness. We think we can create our own Australia or England team by introducing some x factor players. It doesn't work like that.
Our team was gelled in 1992 all the way uptill 2011.
Then misbah came and it became a mess. Players like sami aslam left for USA because as soon as he made his debut scoring an impressive 49 of 49 which was far > Shehzad and jamshed at the time who couldn't even score single digits, but was dropped for no reason.
Same was the case with fawad alam, despite being pur best batsmen via stats and form amd asai cup performances in 2014, YK stole his place by just complaining and doing nonsense and misbah was too timid to do anything.
We were once again unitied under sarfraz in 2017 but after wards even he started doing shady things like going out of hid way to not include rizwan and abid. And this is coming from someone who now hates rizwan for his drama bazi, but I am not biased or blinded by hate, Sarfraz wasn't being fair inn2018 and 2019.
Under babar however we were NOT UNITED. In the asia cup babar threw zaman khan under the bus for not performing in the match he was brought up in, he outright blamed him on media but for shadab and nawaz who the jokes of the tournament he went out of his way to call him his best bowlers.
He also let rizwan make demands and do whatever rizwan wanted and he went out of his way to claim that someone like saim isn't in the world cup squad because he's too inexperienced yet Abdullah who only has played 7 List A games got selected cause babar was just in love with his technique.
During iK and all the way upto afridi's era we the board had control over the team and made it clear they must play for the crest on their chest. AFRIDI is a hard a@s yet in 2011 the committee had a firm hold on him so that he can make a proper team.
However since the misbah era, Pur biggest fault is giving our captains like Misbah, sarfraz, Babar waybtoo much power and the ability to do whatever they want which creates conflict of interest.
It also doesn't help that Shan masood has more power then them as his father literally called babar and told him that shan must play and Bobby needs to lie to the media and claim imam or fakhar is injured to accommodate him in some matches.
We weren't united by any means. I'm not saying it's 100% babar's fault, he's only 20% to blame, it's also pur committee when they make demands like having shan in, or saya corps interference in player selections etc.
