I think the '90s was a missed opportunity. The U.S. was (mostly) at peace, had a lot of tax revenue flowing in, and should have built a safer replacement for the Space Shuttle.
Instead, we continued to rely on a flawed, expensive, and dangerous system to build and supply the ISS. Then, we tragically lost another Shuttle and crew in early 2000s.
