Here are some accomplishments you forgot to mention:

1) Defeated Donald Trump which sharply improved favorability of the United States around the world.
2) Rejoined Paris Climate Agreement
3) Repealed Trump's travel bans and transgender military ban

4) Signed many important legislative acts to help the American people:

American Rescue Plan - To speed up our recovery from economic and health effects of Covid19.
Bipartisan Infrastructure Bill - To fix our roads, bridges, public transit, airports, water ports.....
Reauthorization of Violence Against Women Act.
First major gun safety legislation passed by congress in nearly 30 years.
Chips and Science Act - providing billions of dollars for chip manufacturing and scientific research.
Pack Act - Providing health care and benefits for American veterans.
Inflation Reduction Act - The most significant climate legislation in US history.

Joe Biden in only two years is already the most legislatively successful presidents of the modern era.

Not incompetence. Complicity. Democrats in both houses of Congress did reasonable things to hold Trump accountable. They were competent enough. But so many Republicans, most particularly in the Senate, were complicit with Trump that they were able to block the accountability.

Even aside from that, "months ago" is not very long in the U.S. court system (and probably many other countries' court systems, I would guess). Some cases take years to complete, and Trump the billionaire (or at least arguably a multimillionaire) is able to hire lawyers to delay the process a long time.

Even lots of little cases in the courts, with ordinary people, take years to complete. I can easily recall two such cases which are good examples of that, and a third case which took about a year or a year-and-a-half in criminal court. I can give a few telling details if you're interested; but just as a summary, my first example is my own divorce, my second example is my work supervisor's parent's divorce (an amicable divorce which the court couldn't manage to complete for several years and so one of the couple finally died before it was completed), and the third case (the one in criminal court) (in which bail was set higher than four million dollars) in which I saw both the opposing attorney _and_ the judge (singular) egregiously extending the time; and the judges (another judge, or more than one judge) were otherwise manipulating the time and place until the defendant's friends and witnesses couldn't stay in the process. I know that and more, much of it first-hand, and I'm not even an attorney.

The only thing about Biden, & his culture of corruption, is that he is a meglomaniac, minus the power he would need, to effect the Fundamental Change of Bath House Barry, & "Hussein's regime of destroy America"!

Thank God, there was, & IS", still enough patriots that will not let that happen, under any circumstances!

Yet....Bath House Barry... pulls the strings that make "Puppet Joe", walk, talk, & dance!
