Palestinian Hizb ut-Tahrir

Omran Risheq has an article in this month's Arab Reform Bulletin on the growing influence of Hizb ut-Tahrir among Palestinians. HUT was founded in Jerusalem, but is most associated with Central Asia, where it is the primary Islamist opposition in most countries. However, in contrast to the impression given by Risheq's article, their focus is on establishing a caliphate through peaceful persuasion, rather than a military coup followed by world conquest. I'm not sure what accounts for this discrepancy between Risheq's reporting and everything else I've read about the organization.
