I shared an observation about four or five years ago that I’m now going to repeat, to wit: this is one of the best movie endings of all time — right at the top of the list, I’d say. It’s great and mythic because (a) it explains exactly what the film has been about (i.e., the spreading U.S. paranoia about commies, UFOs and other usurpers of the American dream) without getting preachy, and (b) strongly hints that the worst of the bad stuff is yet to come. And then that hard-slamming Dimitri Tiomkin brass…brilliant!
