Western civilization faces a threat on par with the barbarian invasions that destroyed the western Roman Empire in the 5th century, warns one of Britain's most senior military strategists.
Immigrant groups from the Third World with little allegiance to their host countries could undermine Europe in a "reverse colonization," said Rear Admiral Chris Parry, according to the Times of London.
"Globalization makes assimilation seem redundant and old-fashioned . . . [the process] acts as a sort of reverse colonization, where groups of people are self-contained, going back and forth between their countries, exploiting sophisticated networks and using instant communication on phones and the Internet," he said.
Describing the threats as the new Goths and Vandals, Parry said that along with the migrations could come "barbary" pirates from northern African attacking yachts and beaches in the Mediterranean within 10 years.
"At some time in the next 10 years it may not be safe to sail a yacht between Gibraltar and Malta," said the admiral, according to the Times.
Parry, head of the development, concepts and doctrine center at Britain's Ministry of Defense, delivered the warnings at a conference last week of senior officers and industry experts.
He is responsible for identifying the greatest challenges facing national security policy in the future.
Lawmakers in Britain have made ancient Rome a serious subject of discussion this year, the London paper noted, including a book and television series by parliamentary deputy Boris Johnson drawing parallels between the European Union and the Roman Empire.
Various regions of Europe, Parry said, are threatened by factors such as radical Islam, agricultural decline, booming youth populations, water shortages and rising sea levels.
He believes that from 2012 to 2018 the current global power structure likely will crumble as a result of "irregular activity" such as terrorism, organized crime and "white companies" of mercenaries burgeoning in lawless areas.
Meanwhile, nations such as China, India, Brazil and Iran will challenge America's sole superpower status, Parry said.
The effects will be magnified as borders become more porous and some areas lose government control.
"When one thinks of 20,000 so-called jihadists currently fly-papered in Iraq, one shudders to think where they might go next," he said.
The mass population movements could lead to the "Rome scenario," he asserts, referring to the collapse of the western Roman Empire in the 4th and 5th centuries when groups such as Ostrogoths, Visigoths, Suevi, Huns and Vandals flooded its borders.
Rome eventually was taken over in 455 in an invasion from northern Africa by Geiseric the Lame, king of the Alans and Vandals.
Parry estimates in Britain alone there already are 70 diasporas.
Speaking with tongue-in-cheek, Parry said some of the consequences of this scenario would be beyond human imagination to address, including, "No wind on land and sea; third of population dies instantly; perpetual darkness; sores; Euphrates dries up 'to clear way for kings from the east'; earth's core opens."
Rear Admiral Parry could have mentioned the Viking invasions of Europe, Russia, and the British Isles, Angles and Saxons into Britain after the retreat of the Romans, the Mongols, Turkik nomads into China, the Chinese into Japan, Europeans into the Americas, and the thousands of other migrations and invasions that have occurred over the centuries.
The story is the same: Migration upon migration, invasion upon invasion, have come and gone, and yet, modern man is shocked and surprised to learn that his neighbor finds life at home inconvenient and wants to move in where picking are better to conquer or displace him.
