You and others lack understanding how the federal bureaucracy works and how decades under Obama and others 'silently' packed it with leftist ideologues.
It is easier to beat cancer than it is to fire a tenured federal employee.
For decades, Congress has coddled the federal workforce giving them lifetime job protections, gold-plated retirement plans, and promotions of federal directors based on politics versus competence.
When Trump came to the White House in January 2017, he didn't have the power to select anyone he thought best for the job. He couldn't, for example, have total say over his cabinet picks, that was up to the Senate. Cabinet confirmations were totally political.
Sessions was confirmed because he had been part of the club. Elaine Chao was confirmed because she was married to a member of the club, and so on.
Where Trump had most control was in his political appointees. Dr. Peter Navarro, Stephen Bannon, Kash Patel, Stephen Miller, Russ Vought, and so on. Out of thousands of slots to fill, Trump selected hundreds for the top positions, leaving the rest to others who most often found bodies crawling in and around the Swamp.
Then there are mandated "diversity hires" that forgo true talent and competence in favor of political optics. Notable exceptions are for example, Dr. Ben Carson who was a solid pick as Director of HUD. Congressional politics couldn't touch Dr. Carson. Dr. Carson however, was a rarity.
Similarly, in the military there was a lot of politics. The jousting among flag ranked officers could fill a book under Trump’s watch.
Trump's worst pick could not be seen as the traitor he turned out to be: Mike Pence. This fellow is a defining example of how difficult it is to find persons for DC political positions who are truly intelligent with courage and integrity.
So Trump was betrayed, he couldn't see the choices he made were wrong. Same for Sessions, same for Barr. There was no way for him to see unless he allowed himself to be corrupted by those that make their living in the grift network. No one with noble intent and appreciation for honor could see the depth of the ranks of traitors in and around DC. Trump could not see it all, but he sensed it, and brought Rudy Giuliani to be next to him. Rudy took down the five mobster families in NYC
Pelosi's family in Baltimore were Mafia Gangsters as was Cindy McCain's in Maricopa County AZ. They hated Trump because he had the guts to lure their networks into traps and take them down with people like Rudy in charge:

By Spring of 2018, there had been more than 18 assassination attempts on Trump. One crucial thing that saved his life was his decision to bring his personal security from NYC with him to the White House and keep the Secret Service answering to his personal security.
One thing about Trump, when he made mistakes, he quickly recognized them and took action to correct his mistakes where he could. After Sessions betrayed him, Trump was told Sessions had his best interests in mind. So Trump said "Trust Sessions" (but verify) to his inner circle. That was a mistake. As months rolled by, Trump let it be known Sessions was compromised by DC, aka The Swamp. He could not outright fire Sessions because of Sessions's friends in the Senate. Trump saw the Senate would be needed to be won in 2018 to stop the fraudulent impeachments. Within 18 minutes after winning the Senate in 2018, Trump fired Sessions and replaced him with another traitor Barr because Barr had backing of the Senate.
It's a game of "Heads we win; Tails you lose."
I have always criticized those blaming Trump as like those blaming a girl for getting gang-raped because she wore a short skirt, was popular and trusting. Blame her, not the rapists.
Why did Trump subject himself to this torture? That's a question that history will write a hundred books about. The simplest answer is he loves his country and its people. He saw what was coming. He knew globalists were aligning with the CCP to take down America and the world. He saw all the big players and what they were up to. He knew a war was being planned. He knows many of America's enemies are Satanists, seriously.
As for Fauci, if Trump could have fired Fauci, it would have been done early in the Pandemic. Instead, Trump was able to bring in others to neuter Fauci.
Let's look at some examples of Trump's disgust with Fauci:
President again contradicts his own health expert after doctor highlights troubled US response to virus
“Wrong!” countered the president as he retweeted a video of Fauci making the point in recent congressional testimony.
A few more on Fauci (all from leftist sources):
One more (there are too many examples to list)
Tell people, let's be smart, let's stay silent but watchful, let's watch, observe, and wait for the Truth to be revealed.
“Mafia Gangsters as was Cindy McCain’s in Maricopa County AZ. “
Do you have more on her family? I know they got super wealthy via being the local beer distributors. Of the Budweiser- Busch brand, as far as I know.
