It's obviously super hard to write a concise and unbiased history of the superpower that is the United States in 300 pages, but this book does a decent job of it. It focuses on the facts and doesn't dwell on minute details. Reads easily, and is highly entertaining. My main complaint is that it's a bit sloppy: in some places a sentence directly contradicts the previous one, as if it was not carefully proofread.
Overall, I'd highly recommend this to anyone as an intro which then allows the reader to pick which period they want to learn more details about.
Note: you'll definitely be offended by one take or another because even though the author tried to withhold judgement, when it comes to politics things are so charged that people will inevitably be upset that someone is not presented in a better or worse light. I think Remini did as good of a job as anyone in trying to stay neutral.
One thing that was a revelation to me after reading this book is just how rich the history of the government is in the United States. Literally everything has happened before. Everything that is happening in Congress, Supreme Court, and White House has already happened in the past, and the Founders explicitly thought about it at length (which is unbelievable, really). I didn't quite grasp how dynamic and flexible the American System under the constitution really is until I read all the different permutations happened over the last 250 years. Powerful congress and toothless congress, active executive and a passive one, impartial Supreme Court and an activist Supreme Court. Plus how each branch has a way of restricting the other if enough support can be garnered. For example, President can veto congress lawmaking, but congress can override veto with 2/3s vote. Supreme Court can declare a law unconstitutional, but congress can impeach justices, or amend the constitution. It's really incredible, and it did work its magic at various sketchy times in the past.
It was fascinating to observe how the party politics drifted back and forth. Federalist vs Republican at first, then Federalists disintegrating, but in absence of competition Republican party splits. Whigs and Republicans. Then democrats branch off. Democrats support slavery throughout 19th and segregation through early 20th century, then Republics find a coalition in Christian south and orientation kind of flips. And now another flip happening in real time. Another aspect is mercantilism which is making the comeback now, but it was much on the forefront of the better half of 19th and 20th century debates between parties.
Overall, I feel like like this short history gave me a much needed depth in looking at the current political developments, so I highly recommend this page-turner to all!
