Hizb ut Tahrir are a very confused bunch of individuals.
They appear to live in a fool's paradise. The Caliphate would not be a bad idea in the Muslim world, but everything else is a complete step in the wrong direction. They would try asserting a strict religious code (a backward one in my opinion) that the majority of Muslims, at least in Pakistan, do not adhere to.
Their belief is that they will bring about non-violent revolution by befriending the Pakistani military elite and converting them to their ideology. Hilariously stupid I know, but true. What is sad is that they have a small number of followers (they believe it to be many), that believe this to be true.
One thing the protests in Egypt, Tunisia etc showed, is that a system such as HuT proposes is not wanted, or is a long way away. There was an opportunity for HuT to make inroads into those countries that all fell at the same time. But instead they made none
Following establishment of the Caliphate they would create laws that the majority in the Muslim world, and more importantly Pakistan, do not currently adhere to. They would regard lands outside the Caliphate as Dar-ul-Harb, or permissible to be in a state of conflict with.
So what we have here is that HuT is an organization based around fascism.
