^{The Roman Wall}
I was born in England, in the city of Newcastle-upon-Tyne which is proud of its long history, which can easily be traced back to the period of ancient Rome's occupation of Britain. There are many vestiges of the occupation but the most famous remains are those of Hadrian's Wall. This was a stone wall extending from the east coast to the west coast of England, built to protect the Roman occupied country south of the wall from raids by northern barbarians, or so I was taught. I have never questioned this explanation until recent events have caused me to consider another purpose for Hadrian's Wall.

^{Barrier Only To Unarmed Invaders}
The Roman wall would never have stopped an attacking army, unless it was manned along its whole length. But to garrison the wall in such a fashion would be to undermine the ability of the Roman army to confront a barbarian host, who would invariably outnumber them. Dispersing its soldiers along an 80-mile front could not, and was not meant, to repel a mass attack, but to overcome a problem that Western Civilisation is now facing. It was erected to stop the steady stream of migrants from the barbarian ruled areas entering the Roman Empire. And this was done because even though the barbarians entered the Empire peacefully, they did not come to help the Roman Empire, but to exploit it. They did not want to become citizens of Rome but to retain their own culture within the Roman community, which made them a liability to the Roman Empire.

^{Declining Culture Vulnerable To Parasites}
The impact of the intrusion of an alien culture upon a failing culture is similar to a parasitic attack suffered by any failing creature. Though the citizens of a declining community are slowly losing their attachments to their own community, they still feel some sense of obligation towards it. It is their community, full of their own kind, which is their tribe, so regardless of their growing indifference to their society's tradition, they still feel a concern for its welfare. Whereas migrants from alien cultures have no such concerns; they are among strangers with a different culture. These invaders have not come to improve their host's society, but their own, at the expense of their host. Hence such invading minority communities are parasites upon their host community.

^{Parasitic Nature Of Invaders Initially Masked}
Initially, while the invaders are present only in small numbers, they will treat their host with care and respect. The contempt they must feel about their host's culture will be dissembled, along with their intention to exploit the wealth of their host while avoiding any demands the host may place upon them. They will naturally subscribe to those laws of the host that carry the real threat of penalty or offer profit, but only because of convenience, and not for respect for the notions underpinning those laws; while all other laws of the host community will be silently treated with contempt except in those rare instances where they match their own culture.

^{Incompatible Nature Of Invaders Will Eventually Be Revealed}
As the invaders numbers grow so will their confidence and their own culture will start to publicly assert itself. The invader's general contempt for the culture of their host will become evident and will generate resentment between the different cultures, but while this may fester and flare from time to time, the host will confirm the decaying nature of its own culture by being unable to take effective action against the invaders.

^{A Modern Wave Of Unarmed Invaders}
In the last few decades those countries considered part of Western Civilisation have become subject to an unarmed invasion by other races and cultures. The wealth and safety currently (circa 2001) enjoyed by England, France, Germany, USA etc. have made them desirable places to live for the poor and frightened of other countries, such as India, Pakistan, Mexico etc. While this has been true for a long time, the barriers that previously prevented the citizens of poor countries from migrating to the wealthier countries have been removed. The previous firm resistance by the citizens of the wealthier countries has been undermined by deterioration in the character of their citizens

^{Invasion Flows From Vigorous To Feeble}
Once the citizens of Western Civilisation were determined as well as able, so they dominated the countries occupied by weaker cultures. These subject countries became colonised— they were forced to adopt the language and culture of Western Civilisation— and the superior understanding of Western civilisation was promoted throughout the world, along with its peace and wealth. However as the citizens of Western Civilisation became selfish they lost their resolve, so the control exercised by Western communities declined. This allowed the colonies to recover their independence and re-assert their own culture, which inevitably obtained the poverty and misrule, which had existed before colonialism. As Western Civilisation has abdicated its rule over its colonies, wealth and peace have given way to poverty and anarchy. The example of the social collapse of South Africa has been repeated all over Africa. For many citizens of these colonies, modest means enjoyed in peace have been replaced by a perilous poverty, and the only escape from this misery is to go to where wealth and peace still exist, the home countries of their erstwhile colonial rulers. The tide of influence has reversed. It is no longer flowing from, but to, Western Civilisation; and instead of peace and wealth, it is poverty and anarchy that is now being spread.

^{Invasion Is Colonisation}
The result of this migration is inevitable; the invaders take over their new homeland by sheer weight of numbers. The original manners, customs and beliefs of the destination country are slowly replaced by those of their invaders. This can be easily seen in the USA where the actual border with Mexico is slowly moving further north every year. The culture of the white Americans is being displaced by their mainly Hispanic invaders; peace and wealth created by the white American culture are being replaced by poverty and crime brought by the invaders; a take-over made obvious by the replacement of the use of the English language with Spanish. Miami is now a Spanish-speaking city even though it is technically in America —an English speaking country.

^{Hadrian's Wall in America}
The Americans have naturally tried to halt this invasion but their efforts are weak and ineffectual. The easiest way into America is by walking from Mexico, where a patrolled fence has been erected as a barrier (like Hadrian's wall). Those Mexicans who are detected crossing the barrier are merely returned to Mexico to try again. Those who cross undetected are still subject to discovery but this is an unlikely fate, and the penalty is just a return to Mexico to try again. And often the enforced return can be avoided by manipulation of the law.

^{Mexico now colonising the USA}
Mexico is now (circa 2000) colonising America and imposing its language and culture. Though the Americans still have the strength of understanding to recognise that the Hispanic invasion should be stopped, they are unable to take the measures required to achieve this end. The very least that must be done to halt the Hispanic invasion is the mass enslavement, or execution, of the invaders, which must be followed by an American invasion of Mexico to enforce American language and values upon the Mexicans. But the citizens of the USA recoil from such ruthless violence (see 'the communal attitude to violence') and instead embrace delusion. They pretend their futile defence is not folly, ignore the slow but inevitable takeover of their country and persecute anyone who tries to dispel their illusions. America has lost its ability to defend itself and must eventually be overrun by people from other cultures.

^{Example Of American Failure Repeated}
The example of the failure of the Americans to defend themselves is being repeated by every Western country. Sharing the same lack of ruthlessness required to repel their invaders these countries now find themselves no longer a single community but a group of different communities of varying races and cultures. Even Australia, which is isolated by vast areas of ocean, is being subject to invasion, and while no single Australian city has yet (circa 2001) been taken over, there are now parts of these cities that mimic the original homes of their invaders.

The failure of the Western countries to defend themselves, reveals the powerful understanding once created by Western Civilisation has already dissolved. The two awful signs of impending communal death, the extinction of genius and the loss of the military spirit, are there for all to see. The mainly selfish citizens that now comprise Western Civilisation may still possess the technology discovered by genius, but they no longer have the wit nor the resolution to employ it.

^{Colonise Or Be Colonised}
The simple truth that different cultures are irreconcilable, and one must dominate the others, means the now impotent cultures of Western Civilisation will be overrun. How a particular culture dominates, or attempts to dominate, other cultures, naturally reflects the character of that culture. The fact that the Americans refrain from killing their enemies does not mean that their enemies will refrain from killing them, as America was recently reminded. On September 11, 2001, around 3,000 people were murdered in a barbarian raid upon the USA, when the fanatical followers of an Islamic sect deliberately crashed hi-jacked passenger planes into the World Trade Centre and the Pentagon.

^{The Barbarians Are Coming—With A New Dark Age}
The World Trade Centre attack is confirmation of Arnold Toynbee's claim that the decline of a civilization means the appearance of Barbarian war-bands. And it is clear that, in one way or another, it is only a matter of time before the increasing senility of the countries that make up the Western world, will see them succumb to invaders. The result will be the final extinction of Western Civilization, along with its wealth and power, and a return to the Dark Ages: a time when there is no human community anywhere that is sane.
