They Thought They Were Free: The Germans, 1933-45

Summary Mayer initially planned to go to Germany in 1935 to interview Hitler himself. He failed to secure an interview but discovered, to his horror, that the Nazi movement had more mass appeal than he had previously expected. He decided to switch tactics and focus on the experience of the man on the ground. How does a person, who in most other respects would be considered normal or even good, get swept up in a genocidal ideology? After the war he moved to a small town that had strong support for the NSDAP before, during, and after WW2. He made genuine relationships with 10 of the residents and engaged them in extended interviews. The first half of this book is essentially these interviews, organized into a clear timeline. The second half is Mayer attempting to psychoanalyze Germany as a whole based on what he had learned from these interviews. ...

Balkan Ghosts

This is a cursory look at the countries that have been arbitrarily grouped together since before WW1. He focuses mainly on Albania, Bulgaria, Greece, Romania, and what used to be Yugoslavia. Even though the grouping of “The Balkans” is largely one of convention, Kaplan argues that the suffering and tragic histories act as a glue that makes their stories inseparable from each other. Instead of writing a full review, I’ll relate a story that I found illustrative of the complexities of the region. ...

Alexander Hamilton

After reading biographies of Washington and Jefferson, I was quite excited to read more about Hamilton. I thought he would be a shoo-in for my favorite Founding Father, but the reality of his character proved more complex. Some of my favorite things about Hamilton: He was the first Secretary of the Treasury and the genius behind the creation of American banking and foreign credit. He was a prolific writer, producing the rough equivalent of 70 novels by the time he was 49. ...

Prisoners of Geography

Summary Are you tired of hearing news stories about Kashmir and wondering why Pakistan and India can’t just get along? Can we ever hear any positive news from Sudan? Why does it seem to be in a constant state of turmoil? Why are the borders of some countries straight lines instead of the usual squiggly ones? The world of geopolitics is a complicated place, and there are many approaches one can take to understand it. In Prisoners of Geography, Tim Marshall argues that the most probable route is to look to the land itself for the answers. The main thesis of the book is that there is not enough focus on the ‘geo’ part of ‘geopolitics’. We often spend too much time talking about various ideologies or technologies as driving world events, when reality is often much more affected by land features. For example, on paper it is hard to imagine why the massive empires of China and India have rarely engaged in full-scale conflict—that is until you realize they are separated by the tallest mountain range in the world. This also explains why Tibet is so fiercely contested, as it represents a high ground that neither country is interested in ceding to the other side. ...

The Dark Tower Series

“How does it happen that a writer who’s not even very good—and I can say that, I’ve read four or five of his books—gets to be in charge of the world’s destiny? Or of the entire universe’s?” “If he’s not very good why didn’t you stop at one?” **Dark Tower VII, Chapter III ** Stephen King is the Lay’s Potato Chip of authors. His omnipresence makes him an easy target for abuse. The above quotation captures it perfectly. King is a bad writer, but an excellent storyteller—in the same way that Lay’s makes bad chips, but the kind you can’t stop eating. ...

Ghost Wars

Summary The year is 1979, and Brezhnev authorizes a Soviet invasion of Afghanistan. The USSR had been watching developments there uneasily for years. In 1973, Mohammed Daoud Khan ended the Afghan monarchy. Five years later, on April 27–28, 1978, the Marxist PDPA seized power in the Saur Revolution, launching radical reforms and internal purges that fractured Afghan politics. Moscow was unsettled by the PDPA’s sudden rise, but quickly threw its support behind the new regime. The PDPA’s rule proved unstable, dominated by a radical faction that tried to secularize society and overturn centuries of tradition—sparking a conservative Islamic backlash. This had broader implications for the USSR, which contained its own Muslim-majority regions. Moscow was unwilling to stand by and risk a conservative revolution spreading across its southern flank. ...

Thomas Jefferson: The Art of Power

Summary America’s third president was a citizen of the world. An idealist in values, but ruthlessly pragmatic when in the seat of authority. Jefferson was in public service for about fifty years, with his influence lasting directly up to Jackson’s presidency, making him one of the most effective political operatives in American history. Meacham gives a full view of Jefferson’s life from early education to his end-of-life correspondence with Adams. Jefferson cuts one of the most romantic and contradictory figures in early America. To the rest of the world, he displayed a certain sophistication many thought impossible to emerge from the Americas, whereas to history his regressive stance on slavery taints his memory: he at once acknowledged its illegitimacy yet could not bring himself to reject the peculiar institution altogether. Jefferson was the most vocal of the founding fathers in his defense of the individual rights of man (though, of course, definitions of “men” varied), and this manifested in an expressed distrust of strong federal governments. The preference for small government formed the basis for his antagonism with America’s other premier intellect, Alexander Hamilton. This disagreement ended up forming the first political parties in the US, the Federalists (Hamilton’s party) and the Republicans (Jefferson’s party). The founding gets mythologized for obvious reasons, but it is truly remarkable that two such politically fertile minds as Jefferson and Hamilton would be selected to form this country’s first cabinet. It is also a testament to Washington’s leadership that such a cabinet could exist for as long as it did. Always sure that Washington was Hamilton’s puppet, Jefferson would eventually retire to Monticello in a semi-theatrical way. His avowed aim was to put the dirty work of politics behind him, but both Washington and Hamilton suspected that Jefferson was “protesting too much.” Their suspicions turned out to be correct, he would shortly be back in office, serving a single term under the acerbic John Adams as vice president. He would then deftly create the first single-term president in US history, ascending to the highest office in the land. Once in the driver’s seat, strong centralized authority seemed useful, and Jefferson did little to curtail the powers of the executive. In fact, when Napoleon offered Jefferson the Louisiana Purchase, he was worried that the purchase of lands was not within the scope of Federal authority and would require an amendment. He ended up deciding the amendment path would open the purchase up to an extended window of debate and deliberation when decisive and quick action was needed, and so he pushed the purchase straight to Congress. This is not to say that Jefferson’s values were inauthentically held; it was more a testament to his adaptability. After Jefferson served two terms, the presidential office went to his long-term friend and ideological ally Madison. He would keep in close contact with leaders of the Republican Party for the rest of his life. ...

Washington

Fantastic biography. Washington was absolutely instrumental to the birth of the US. It is hard to imagine the country having survived with any other leader at the helm. Although he was vain, insecure, and not the brightest in the pantheon of the founding fathers, his heroism and commitment to the ideals of liberty more than make up for any personal short comings.

Democracy in America

This is a great book to build a functional understanding of the how and why of the U.S. government. The first volume is fantastic; the second one is slightly more speculative but still full of good insights. Much has changed since the writing of the book in the 1830s, although one of de Tocqueville’s central claims—that Russia and the U.S. were destined to be world powers—has panned out quite nicely. Instead of a full review, which would be insanely long due to the length and breadth of the book, I’ll leave some scattered thoughts: ...

The Secret of Our Success

I had written an extensive review that was erased. Here is a really good one from an expert in the field. https://drive.google.com/file/d/10W5lAhu_QmXTfCjzGwg6-3S_bi05NkGo/view The short version is ape alone weak, ape together strong! The secret our success is our ability to leverage the smarts of an entire society instead of relying on individual brilliance. As Henrich says: “We stand on the shoulders of a very large pyramid of hobbits”. One way to drive this intuition home is to take a minute and try to imagine which objects around you, could you, if stripped of all experience re-invent. Looking around, I think the only thing that made it on my list was a cup, and that is probably being too generous.
