Regardless of whether you prefer Trump or Biden, I don't get this trend of making last-minute US policy changes before Trump sits in. Can't he undo all that once he becomes President? If so, what difference does it make?
Having opportunities to change things after being voted out seems to be a bad oversight to me. The difference is time and effort. If the outgoing administration doesn't do anything else, you can already setup your agenda and timelines for things you want to accomplish, tossing stuff in can derail your agenda and/or timing. The outgoing president is still president until the incoming one is sworn in though, so that is what you deal with.
Should the highest office in the land just go on pause? People voted for the previous president knowing they would be in office almost 3 months after the next election results.
Yeah, that's a valid argument.
Would you say the same about Trump's last minute changes in Afghanistan before he left office for Biden to take over? In this case, Trump removed the vast majority of troops in the interim period, leaving Biden with a situation where the number of troops still left were insufficient for the tasks at hand
Sure I would.
I certainly don't disagree with the idea that the interim period ought to be shorter, but I would push for shorting the election down to 3 months as a better priority
