He's sleepy, he has dementia, etc.
I would rather not have the best leaders rule by themselves like your MBS for example and do stupid shit like build the Line City, vs a not-good leader who has competent advisors which Biden has in spades.
The best leader unchecked by his peers will make bad decisions. I would argue MBS vs his father and various others like the king of Jordan is a philosopher king in every sense of the word, the problem is he thinks he knows best.
The best leader checked who is smart enough to have stubborn views like your Obamas will pull the US in a direction that they find will create problems in the future. Look at President Obama he deported millions of hard-working Hispanics to appease Republicans versus listening to his advisors even at the University of Chicago about the benefits of immigration. He created the ACA without a public option funded by itself to appease the insurance industry, which has led to Congress having to do healthcare policy by treading on thin ice ever since then.
The best decisions happen in aggregates of multiple shareholders of diverse backgrounds who want to get shit done. Not like shareholders who want to fire people to increase the stock price like in business, actual experts who don't play games with the lives of others. Lula and Biden are the prime examples of this. They aren't Superman micromanagers.
The website's failures and the scramble to correct demonstrate most the president's administrative struggles.

Gates said the Obama White House too often let politics influence the policy when it came to the Defense Department.
