Empires come and go. Nothing is for eternity. By 1750 the Western imperialists (not using this word in a negative way) have started the colonization process already and Islamic powers were in decline. It's not Islams fault, the same religion that gave us enough power to overrun global powers few centuries earlier.
Are you even Muslim? Or are you an "I-am-a-Norwegian-trust-me-bro-my-brown-skin-is-a-just-tan"-Pakistani? You can learn from history. My take on the caliphate is that Allah showed us that NOBODY is perfect, we are all capable of making mistakes, even the first Muslims. You can cry all day long why the Rashidun caliphate lasted for 30 years or try to act on the path of the Prophet (PBUH).
Are you a data scientists or something?
Pakistani Islam = Islam, Islam when we can opress our own children but all hail Murree Brewery when we can get a Rupee or two from that. Yes, totally Islam is at fault here.
