Dunbar-Ortiz is one of our era's most important historians, and while you'll probably be depressed after reading this, it's an essential takedown of the "nation of immigrants" myth. Dunbar-Ortiz reviews the historical background of that phrase and why it was employed by JFK, then systematically works through the history of the US and shows that, rather than immigration, the US has been consistently defined by settler colonialism and white supremacy. It's a powerful, extremely well researched book, but be warned you probably won't be able to enjoy "Hamilton" again after reading this. It was also a bit short on potential responses to these injustices, but to be fair that's not the aim of the book. Highly recommend
