Londonistan calling from the faraway towns, now war is declared and battle come down.

The British branch of a world-wide radical Islamist group, Hizb ut-Tahrir, held a conference London on Saturday, in which speakers called for the overthrow of Muslim governments and their replacement with a single Islamic state, known as the caliphate. According to Hizb ut-Tahrir's website, "thousands" of people attended the conference.

Hizb ut-Tahrir - the Liberation Party in English - is active in dozens of countries, but has been banned in several Arab states, as well as European countries such as Germany and Russia. It is also illegal in China. In Britain, the organization is still legal, despite instances of the group's members and websites being found to promote anti-Semitic incitement to violence and calls for suicide bombings. In Australia, the organization is facing the prospect of a ban.

David Davis, writing in the Times of London (or should I say the Times of Londonistan?) says Hizb ut-Tahrir (HuT) is an enemy of Western democracies.

The British suicide bombers who attacked Mike’s Place in Tel Aviv in 2003 had Hizb ut-Tahrir contacts. Terrorist fixer Mohammed Babar (who turned and testified against the Crevice July 7 bombers) was a member. Shoe-bomber Richard Reid was influenced by HuT preachers. And Omar Bakri Mohammed, a former Hizb ut-Tahrir leader – now deported to Lebanon – believes that 7/7 was the fault of the British people and describes the 9/11 bombers as the “magnificent 19”.

And that is just in this country.

Across Europe, Africa, Asia and Australasia, HuT preaches a virulent brand of Islamic extremism. Senior Al-Qaeda leaders, including Abu Musab al-Zarqawi and Khalid Sheikh Mohammed, were members of HuT. Its UK website boasts that it is a “global party”, directly associating itself with the acts of its branches abroad.

In response to the recent attempted attacks in London and Glasgow, HuT confined itself to this general legalistic comment: “We reiterate our position that Islam does not allow the harming of innocent civilians.”

So were those targeted at Glasgow airport and the Haymarket “innocent” or “guilty” civilians? This deliberate ambiguity is telling.

How about deporting these people? Isn't their statements like nature's way of telling you that you face a threat to your lives and ought to take appropriate actions? Hello? The non-citizen Muslims could all be told to leave pronto. Then the citizen Muslims could be offered a buyback of their citizenship. This problem is solvable with sufficient will to solve it. Or do the British prefer "getting hit on the head lessons"?

100 Muslim school children in Britain are taught Hizb ut-Tahrir beliefs in a united Islamic caliphate worldwide theocratic empire.

Members of a radical Muslim group that Tony Blair promised to ban after the July 7 bombings have set up two schools in Britain to educate primary age children.

The Islamic Shaksiyah Foundation, a registered charity that runs private schools in Haringey, north London, and in Slough in Berkshire, was established two years ago by female members of the extremist group Hizb ut-Tahrir.

HuT is big on doctors and engineers. Do I need to mention that engineers could make more effective bombs?

Yesterday Attorney-General Philip Ruddock signalled that authorities were looking at the Hizb ut-Tahrir group, which is currently legal in the UK and Australia.

Mr Ruddock was speaking after a Hizb ut-Tahrir defector from the UK, Ed Husain, warned Australian authorities to look at the group and said its leadership included a large number of doctors and engineers.

Ed Husain thinks there's a difference between Islam and Islamism. By contrast, ParaPundit thinks there's a difference between people who embrace the core beliefs of Islam and those who believe in watered down and impure variants of Islam. It is the believers in the diluted versions of Islam that do not want to dominate or kill non-Muslims.

If Londonistan radicals were all deported they would become more circumspect under the watchful eye of Middle Eastern rulers.

TRIPOLI, Lebanon: There was a time when Omar Bakri Mohammed embodied every stereotype of the jihadi extremist. From his perch in London, he threw around words like "kafir" - infidel - to describe Christians and Jews and openly praised the bombers of Sept. 11, 2001.

But sitting recently in his new library overlooking Mount Lebanon in this northern city, with a bloody battle raging between the Lebanese Army and the Qaeda-inspired Fatah al Islam at a Palestinian refugee camp a few kilometers away, Bakri presented himself as a changed man. Whether the shift is as meaningful as he asserts is an open question.

He speaks of peace, decrying the unnecessary use of violence and emphasizing the sanctity of life.

I decry the unnecessary tolerance of Muslim violence in Western countries by Western rulers.
