The founder of HT, Taqiuddin al-Nabhani, spent much time discussing the nature of thought, but such sophistry is limited by its dogma. He believed that Islam was rational and therefore could be promoted through persuasion and rational discussion. Contradicting this, he maintained that the Koran cannot be questioned, and is thus beyond the bounds of true discussion. Persuading non-Muslims to accept Islam as a political system which allows no dissent from the tenets of one book would naturally result in conflict. This conflict was specifically alluded to on the group's UK website last November (since removed). The statement claimed that Hizb ut-Tahrir "also aims to bring back the Islamic guidance for mankind and to lead the Ummah into a struggle with Kufr, its systems and its thoughts so that Islam encapsulates the world."
For Nabhani's successors in Hizb ut-Tahrir the "non-violence" paradox is not resolved. The dogma assumes that there can be rational discussions to implement a non-negotiable fundamentalism. Violence is officially eschewed, but HT promises that all social and political ills would be solved under a Caliphate, as explained in a tract I took from their UK website in 2005: "Its aim is to resume the Islamic way of life and to convey the Islamic da'wah to the world. This objective means bringing the Muslims back to living an Islamic way of life in Dar al-Islam and in an Islamic society such that all of life's affairs in society are administered according to the Shari'ah rules, and the viewpoint in it is the halal and the haram under the shade of the Islamic State, which is the Khilafah State."
How people would live under such a Caliphate is spelled out in detail in its "draft constitution" (for the proposed Caliphate). Within parts of the Islamic world (Dar al-Islam, the "abode of submission") it may be possible to persuade Muslims to achieve such goals, but for democratic, non-Muslim lands (Dar al-Harb, "the abode of war"), or even democratic or clan-ruled Muslim lands, implementation will be harder to achieve without violence or extensive manipulation.
GlobalSecurity.org succinctly describes HT's proposed three-step strategy: "The first involves educating Muslims about its philosophies and goals. In the second step, the Muslims would then spread these views among others in their countries, especially members of government, the military and other power centers. In the third and final step, Hizb ut-Tahrir believes its faithful will cause secular governments to crumble because loyalties will then lie solely with Islam - not nationalities, politics or ethnic identifications.
Effectively, the strategy will involve indoctrination, infiltration, and undermining national stability. The arrival of Hizb ut-Tahrir in the Central Asian republics exemplifies all three modes, particularly undermining stability. In Tajikistan, for example, HT arrived in a country already destabilized
