pk.gifThe indomitable Arnaud de Borchgrave — 81-years old and still providing the world with invaluable investigative reporting — has an important piece in The Washington Times aptly called, Pakistan's Terror Inc.

De Borchgrave reports that some 400,000 Pakistani Brits fly back and forth between England and Pakistan each year. Those who visit terrorist training camps do so undetected, which presents MI5 with an enormous security challenge.

"Most terrorist trails lead back to Pakistan, Britain's MI5 (internal intelligence service) concluded a year ago. An average of some 400,000 Pakistani Brits a year fly back to the old country for vacation or to visit their relatives. From the airports in Karachi, Lahore and Islamabad, where they land, side trips to the madrassas — Koranic schools — where they were originally radicalized, or to a terrorist training camp in the tribal areas that straddle the Pakistani-Afghan border, go undetected.

There is no way to keep track of thousands of passengers arriving from the United Kingdom every day. Nor can MI5 cope with up to 1,000 a day returning to their U.K. homes from trips to Pakistan."
