Correct me if I'm wrong, but isn't the history of Islam to invade countries and take over completely? Isn't that what the Caliphate was about?
"Hizb ut-Tahrir promises that a revived Caliphate will end corruption and bring prosperity - though the group doesn't say how. It will let Muslims challenge, and ultimately conquer, the West, its followers say.
"The Muslim world has resources like oil but it lacks the leadership that will rule us by Islamic law and make this jihad that the whole world is afraid of," says Shakr, a Jordanian member of the group, who says the success of the Caliphate will also encourage more converts to Islam - eventually making the whole world Islamic."
Islam is to Democracy (and Democratic countries) as a virus is to the human body.
