Nothing is as wrong as Pakistan as phoren-based Pakistanis tend/love to project- Like you, if you love Pakistan and Islam, why would you like others to use nukes on your own awan. Saudi Arabia, Sudan and Northern part of Nigeria have Sharia and all of them are rich, successful countries. After all, Pakistan was created in the name of Islam- Islam and sharia can't be separated from each other. Even if Taliban takes over Pakistan, I don't think anything is wrong in it.
The Saudis have oil wealth. They are not successful through the fruits of their man power/labour.
Nigeria has oil, yet if you think they are successful, think again. They are even poorer then South Asian countries!
Sudan is a basketcase!
