She doesn't answer to anyone; that is the problem - Biden for what its worth seems to have tried to get her to cancel, as did regional allies (given the level of person from them she's been greeted by up to this point). Obviously she considered her "legacy" more important than starting a fire in the mother of all tinderboxes, and lets not anyone be surprised by how inept that was. She (along with the rest of the shower like Schumer) should have been disposed of in 2016, but no and so she's been left in post to do this, and to screw up two impeachments (the second of which is in my opinion the greatest peace of incompetence of the 21st century to date).
As for the current administration vs Trump - Trump's ineptitude is still being felt in all these decisions (not doing anything with Russia; messing with China and Iran pushing them further into the orbit with Russia). If anything the lesson here should be to get rid of this cult of the elderly that has seized control of politics.
Politicians need a mandatory retirement age of 65, and to be honest I'd take the vote away from everyone over 65 as well at this point. Many of them are still sound but there is a huge proportion across the West who are repeatedly voting for the destruction of their children and grand-children, and they need to be prevented from doing that.
