A、Because Americans are proud of their own country B、Because flags go up everywhere with an abundant sense of patriotism C、Becau

One year after the September 11th attacks on New York and Washington, some of the changes are all too obvious. This is now a very security conscious nation. The feeling of safety provided by two mighty oceans is now gone. Americans no longer get on planes as if they were buses or go to baseball games without a brash from a metal or explosives detector.
    But as Dr. Matthew Spalding of the Heritage Foundation points out, alongside fear there is also pride, patriotism and a new sense of purpose.
    Dr. Matthew Spalding, "I think Americans have changed considerably. September 11th of last year, flags went up everywhere; a sense of patriotism abounded. A year later it’s a sense of a mellowed patriotism, a thoughtful patriotism. Americans aren’t afraid to be patriotic and want to think about it.
    Secondly, I would say Americans are more thoughtful about foreign policy and domestic policy and, thirdly, I would say Americans are looking inward to things that are important to them: their families, their churches, service in their community--things that in the long run will be good for them and their families and their lives."
