You want to know why Dave has come out now and said that multi-culturalism has not worked ?
Its because the security services have just informed him that due to their policy of allowing London to become the base of the global jihad under the 'covenant of security' whereby the Middle East regimes run by the oil monarchies were allowed to dump their radical islamists in Britain using our asylum system, we now face a terrorist campaign that will span the next thirty years and could possibly lead into a civil war at some point.
Since the fall of the British Empire all the ex-British Empire oil producing nations in the Middle East, like Saudi Arabia, Yemen and others who were allies of Britain, have all been allowed to deport their home grown Islamist terrorists into the United Kingdom where they were all then given asylum by the British government.
Then M16 was able to infiltrate them and monitor them and use their agents to control and infiltrate the Islamist movements in those nations, thereby ensuring the royal families who run them continue to run them - and the oil and oil profits continues to flow to buy British weapons produced by British arms manufacturers.
In exchange for Arab oil, we became the dumping ground for their Islamist terrorists.
Those Islamist terrorists dumped in the UK were allowed by successive British governments to organise the global jihad from Britain, and in particular Londonistan, and British citizens of foreign descent were allowed to leave Britain and go to Afghanistan, Pakistan and other areas to train to become Islamist terrorists and undertake jihad.
The SAS trained the KLO in Kosovo.
The CIA set up and armed Al Qaeda.
This was the covenant of security, whereby the terrorists were allowed to act with total impunity and in return they did not attack Britain, restricting themselves to terrorism and murder elsewhere in the world.
Now that covenant has been broken.
A whole wave of radicalised Islamists terrorists is now about to undertake suicide bombings and terrorism in our country.
Thats the result of liberalism and multi-culturalism.
Terrorism, war, murder, bombings and beheadings.
That is why we must not just destroy the entire multi-cultural system - we must make such a task a matter of National Security.
