With their innate knowledge of the country's psyche and the ease with which they can travel the country without being detected, the U.S. passport-carrying terrorists have become a nightmare for counter-intelligence agents (emphases mine)
So, now we have global unease directed at that heretofore unlikely candidate - the American international traveller. Since the end of the nineteenth century, but definitely since the end of the Cold War, the American traveller has been a pampered, fussed-over specimen, roaming freely like the bison of the Great Plains, or like the deer or the antelope of said Plain. Whether outrageously wealthy or just comfortably middle class (poor Americans tend to staycation), the arrival of the American wanderer on foreign shores was greeted with cries of joy by peddlers of counterfeit and luxury brands alike. His or her presence drove up the local prices of taxicabs, household help wages, and brought about the global availability of ketchup. Visa rules were changed or bent for the convenience of this usually genial (although somewhat sartorially challenged) traveller and the non-reciprocity of entry rules for people wishing to enter the United States was seen as understandable (after all, everyone wants to go to the land of milk and honey, right?). American travellers swanned through entry points, checkpoints and sometimes, customs bureaus.
Now, though, international terrorism is changing all that. In the days before 9/11, the bad guys looked, well, brown and Middle Eastern (or Slavic), they couldn't possibly be American, right? And blond-haired, blue-eyed men and women must be on the side of the angels, right? These days, though, innocence no longer looks exclusively European and villainy no longer comes only in darker shades of skin tone. An American passport and a gleaming set of well-tended American teeth are not anymore an automatic guarantee of welcome all over the world. Already, India has put into place stringent new rules about the entry and exit of foreign nationals, global investment opportunities be damned. I mean, when it's a choice between the lives of your own citizens and the ease of entrance for some unknown American, which would you choose? Add to this a suspicion about the real motives of American citizens abroad (for example, are they really taking innocent tourist shots with their expensive cameras, or are they doing a recce of potential targets for terrorist strikes?), throw in a growing perception that the United States is flat broke, deep in debt and in general global decline and then I think, at least in the medium term future, distrust of the American traveller will be a scenario throughout the globe. American globetrotters, don't say you weren't warned: be ready to wait in line at immigration and customs, and prepare to be scrutinized much more closely
