The country name is the Islamic Republic of Pakistan. They have their own Islam which has got nothing to do with Islam Deen of Quran.
There was a hypocrite and liar Army General President Zia ul Haq who signed the bill to execute who so ever inflicts insults in honor of Prophet (S). In fact, there is no such verse in Quran about the Prophet(S). Allah (SWT) knew that his slave because of some ups and downs in life, may revolt but HE left his doors open for all to repent.
According to Quran Zia ul Haq must be having a good time in hellfire for disobeying Quran.
