Hizb ut-Tahrir is dedicated to what it sees as the political unity of Muslims, the removal of what it considers to be neo-colonialist Western control of Muslim lands, and a return to a state based on Islamic law (Sharia). In accordance with that, the party has called for Muslims to overthrow their governments, establish the caliphate, and declare jihad against Israel. The party has called suicide bombings in Israel "legitimate" acts of "martyrdom." 
Although the party is banned in many Arab countries, it is permitted to operate in the more liberal UAE, Lebanon and Yemen. It is also banned throughout the former Soviet Union states of Central Asia and its activities are banned in Germany (though the party itself is not). It operates legally in most Western nations and survived a ban in Australia after clearance from the Australian Security Intelligence Organisation. On August 5, 2005, Tony Blair announced the British government's intention to ban the group in the United Kingdom.
