For the many quirks in the Trump administration, one has to recognize: Bridenstine did a good job, and more generally, Artemis is on far better ground that STG 1969, SEI 1989, or VSE 2004.
This, for a simple reason: massive participation of private space companies into NASA new venture. This is of paramount importance, because that private slice of Artemis is independant from Congress.
Even if NASA budget is starved or slashed, a company like SpaceX (also Blue Origins) had plenty of separated business opportunities elsewhere. SpaceX notably, is fueled by satellite launch contracts and Starlink cash cow, obviously.
In turn, this makes Artemis harder to cancel or starve of money. Just like in the ISS, foreign partners and their international agreements made it cancellation-proof in the 90's.
Now let me tell you something funny. Since 1969 and the death of Apollo, space nerds longued and wished for a new JFK and/or a new "JFK Apollo moment". Every single new US president was scrutinized to see his "NASA credentials". Well, most of the time, it failed - STG, SEI, VSE went nowhere.
Now that Artemis has enlisted private companies, it has far better chances to succeed.
...and I find it both funny and a little unnerving that Trump, of all presidents, did THAT.
This doesn't intend to start a flame war: I'm not American, but I'm a space nerd who is impressed and respecful of NASA achievements.
The space agency is really America as its best: admired and respected for its prowesses by foreign countries. The United States we like.
