Thomas Friedman:
A few years ago my youngest daughter participated in the National History Day program for eighth graders. The question that year was “turning points” in history, and schoolchildren across the land were invited to submit a research project that illuminated any turning point in history.

My daughter’s project was “How Sputnik Led to the Internet.” It traced how we reacted to the Russian launch of Sputnik by better networking our scientific research centers and how those early, crude networks spread and eventually were woven into the Internet. The subtext was how our reaction to one turning point unintentionally triggered another decades later.

I worry that 20 years from now some eighth grader will be doing her National History Day project on how America’s reaction to 9/11 unintentionally led to an erosion of core elements of American identity. What sparks such dark thoughts on a trip from London to New Delhi?

In part it is the awful barriers that now surround the U.S. Embassy in London on Grosvenor Square. “They have these cages all around the embassy now, and these huge concrete blocks, and the whole message is: ‘Go away!’ ” said Kate Jones, a British literary agent who often walks by there. “That is how people think of America now, and it’s a really sad thing because that is not your country.”

In part it was a conversation with friends in London, one a professor at Oxford, another an investment banker, both of whom spoke about the hassles, fingerprinting, paperwork and costs that they, pro-American professionals, now must go through to get a visa to the U.S.

In part it was a recent chat with the folks at Intel about the obstacles they met trying to get visas for Muslim youths from Pakistan and South Africa who were finalists for this year’s Intel science contest. And in part it was a conversation with M.I.T. scientists about the new restrictions on Pentagon research contracts – in terms of the nationalities of the researchers who could be involved and the secrecy required – that were constricting their ability to do cutting-edge work in some areas and forcing intellectual capital offshore. The advisory committee of the World Wide Web recently shifted its semiannual meeting from Boston to Montreal so as not to put members through the hassle of getting visas to the U.S.

The other day I went to see the play “Billy Elliot” in London. During intermission, a man approached me and asked, “Are you Mr. Friedman?” When I said yes, he introduced himself – Emad Tinawi, a Syrian-American working for Booz Allen. He told me that while he disagreed with some things I wrote, there was one column he still keeps. “It was the one called, ‘Where Birds Don’t Fly,’ ” he said.

I remembered writing that headline, but I couldn’t remember the column. Then he reminded me: It was about the new post-9/11 U.S. Consulate in Istanbul, which looks exactly like a maximum-security prison, so much so that a captured Turkish terrorist said that while his pals considered bombing it, they concluded that the place was so secure that even birds couldn’t fly there. Mr. Tinawi and I then swapped impressions about the corrosive impact such security restrictions were having on foreigners’ perceptions of America.
