Biden had 8 months to fix the situation. He has been in government for 50 years and has screwed up the entire time. The only good thing out if this. Is we will get Trump as president to fix this mess.
If Trump becomes President again then this will become Nazi Germany. I would suggest you look at the California recall election. Newsom is not popular but he will likely win by a margin pretty close to what he won by in 2018. This will happen because the leading candidate to replace him was a Trump like right winger. Biden's only mistake was feeling he was bound by Trump's agreement which the Taliban had already violated.
