If islam isn't barbaric, why are islamic countries barbaric?

I'm talking about Countries with Islamic law and Islamic religious standards. In UAE, a traveler was a house guest to a Arab business man in Abu Dubai, he had a recent knee surgery, he bring vicidin in luggage without the prescription bottle. He was immediately arrested for drug charges. He can be given the capital punishment because of the Islamic moral laws. In Pakistan, a Diplomat was arrested and sentenced to death for blasphemy because she defended Christianity in a conversation with a Muslim. You can be arrested in Saudi Arabia for carrying a bible or proselytizing. You can be beheaded if you practice Astrology in Saudi Arabia because your accused of being a sorcerer. Why would Muslims what Sharia laws in western countries when Muslim governments are barbaric?
