Twenty-five years is a long time. Long enough for a generation to grow up never knowing a pre-9/11 America — no TSA lines, no Patriot Act, no forever wars. Yet for millions who lived through September 11, 2001, the images are still instant and visceral. The twin towers, the Pentagon, a field in Pennsylvania.

The policy choices made in the weeks after 9/11 can now be judged with real historical distance — and the verdict is complicated.

The question worth sitting with isn't just what happened that day. It's what America chose to do next, and whether those choices made the country safer or simply different. Continue reading at Reuters.
