It's a myth that Americans are not willing to undergo questions and waits given the safety risks. The media are the only ones you ever hear saying that the public will not put up with it. They're looking for a story and some controversy where there is none.
Americans are willing to put up with effective security screening by well-trained, high quality, decently paid security personnel a la El Al. What they are not willing to put up with is bogus, incompetent, and pointless "screening" by unmotivated, low quality, not-so-well paid airport personnel.
Since just as many seem to be flying as ever, you're probably right.
