Yes, Taliban would provide sincere leadership. Btw, often religion is the problem. (West) Pakistan population has gone from 35 million in 1947 to nearly 200 million today. How about encouraging contraception and family planing? Would Mullahs allow that? Oh, wait they want child brides and use religion justify it.
