Earlier quoted context omitted.
The Artemis plan was originally to return to moon by 2024, and the first crewed flight is still planned for next year, so it seems entirely reasonable for a President that's in office from 2024 and 2028 to want it to actually happen within that time frame. Since, you know, that's been the established and agreed upon plan for nearly a decade now.
2024 was never considered remotely realistic by anybody in the "industry"---it was a purely political deadline and the will/funding was not there to achieve it. Today (AFAIK) 2028 is considered quite aggressive, mostly due to the lack of progress on Starship, and the facts driving that conclusion are not any more amenable to change via political pressure than they were last time.
Bean counters make excuses. Put the right people in the right places and shit gets done.
