I have been surprised how few people seem to gave taken the lesson from Trump that creating federal authority today empowers all future leaders.

Courts have slapped down some of Trump's actions thankfully, but a lot of what he has done that many disagree with simply shouldn't be legal and only are because in the past we had what may have been good reason to solve a short term problem.

Trump shouldn't have been legally allowed to enact a war without congressional approval before it began. As it stands he was able to sneak through with the war powers act, congress is completely unwilling to enforce their own oversight authority, and Trump eventually redefined how to interpret the war powers act and again congress rolled their eyes and didn't challenge it.
