This book takes its title from Majorie Taylor Greene's conspiracy theory about a forest fire, which made a nod toward the anti-semitic conspiracy theory but didn't precisely say 'Jewish space lasers'. That's just the on-ramp though: it's mostly a history of the Rothschild family (of no relation to the author). Which I found pretty interesting, but at times a little dull because I honestly find most pure-history books dull.
But there were highlights, and as far as I can tell it's one of the first books to give an honest reporting of the Rothschild family, so it's serving a purpose.
Lots of what I've read touches on this point, but it's an important one: anti-semitism really is an immortal, powerful force in history. I find it really hard to wrap my head around. But it just keeps going, and it's so much more widespread in other regions. From a 2006 Pew Research article:
Of course, negative attitudes towards Jews are not uncommon in the region — in neighboring Jordan, zero respondents had a favorable view of Jews, and Morocco and Pakistan also posted favorable ratings for Jews in the single digits.
I felt like this book sped up near the end where it started discussing modern-day theorists and politics, and that was kind of a bummer because that material really helps anchor the rest of the book in the familiar and immediate.
If I liked history books, this probably would have been a 4. Especially if you're expecting it to be a snappy page-turner, you'll be disappointed, but it's a good topic and a good book about it.
