Who really knows?
But I tend to disagree with this post of your's about the American involvement. I see little reasons for American meddling in Pakistan, especially after the American withdrawal from Afghanistan in August 2021-- Pakistan is a potential 'useful fool' for America to needle India if and when needed. Also, Americans know where the real power lies and CPEC, as well as relations with China, are too important for Pakistan to let America dictate major changes. Maybe Biden didn't care for Imran on personal level but not the point of 'regime change'.
Imran's removal had to do with Pakistan's domestic reasons. I think Imran was brought into power as a 'manageable' asset by the Pakistani military which was disillusioned with PPP and Noon League. While the 'Project Imran' had started in early 2010s, the Noonies were too popular in Punjab and so managed to win the 2013 elections. But soon after that, Imran was put on a path, aided by the Muscle-Power of the Imported Mullah from Canada Mr. Tahir ul Qadri, to topple the Nawaz govt. That too didn't work because, among other reasons, such as all other political parties closed ranks and supported Nawaz, and top leaders supporting Imran like Javed Hashmi backed out when realizing the military was supporting Imran in the 2014 agitations. But the military ultimately managed to remove Nawaz from power. It was all basically domestic reasons.
And to re-emphasize: There is an extremely low chance of Imran being co-opted again by the military in future to be part of some power-game; Imran has burned his bridges with all and probably even with his current (3rd) wife! Such a 'leader', isn't it??!! As long as the Pakistani civilians focus on the economy and governance and keep hot-heads like Nawaz Sharif away from the topmost spot, I see stability and even some kind of revival in Pakistan into next several years.
