Btw, I completely agree with your observation about the alleged decline of the West and China's rise. Anyone who has interacted with Chinese individuals will quickly realize why they are unlikely to achieve the same level of global soft power (and dominance) that the West, particularly the United States, possesses. Their demeanor tends to be cold, robotic, and highly transactional.
Pakistan is fortunate to possess two characteristics that make it appealing to the Chinese Communist Party:
It is a nuclear-armed military power and, due to its strategic location, serves as an emergency escape route for Chinese goods should the US ever decide to close the Strait of Malacca in case of war.
I recall watching a Franco-German documentary that delved into the China/US rivalry. A Chinese professor of International Relations spoke very openly on the subject during an interview, highlighting that America's status as a global hegemon is largely due to its extensive network of allies and international relationships, which China notably lacks.
What I am trying to say is: the West is here to stay. Any pro-IRI person suggesting otherwise is merely crafting a rationale for the day when the current regime resorts to brutal measures against its own citizens to maintain control.
