Short, but packed with long-term knowledge and wisdom. I've long been a fan of the three authors: Ryan Hass (former NSC China Director), Bonnie Glaser (long-time think tank expert at CSIS and now the German Marshall Fund), and Richard Bush (former Chairman, American Institute in Taiwan). Anything they write is worth reading and considering. Collectively, but also on their own merit.
If you were to read one book on U.S.-Taiwan relations, then this would be the book to read. It is rooted in history, considers the present-day circumstances, and humbly looks to the future. And best of all, it thinks about how China fits into U.S.-Taiwan relations. The second compelling point is that the book has only 130 pages of text (including chapter endnotes). The reference materials and appendices make it a nice handbook/educational material, but still only bring the total length to 177 pages.
H.G.B. (the authors) argue that U.S. interests are best served by deterring unilateral changes to the cross-Strait status quo. This means enhancing military deterrence to raise the price China would pay to forcefully seize Taiwan. It also means encouraging Taiwan to better defend itself and focus on building a healthier, more globally-integrated economy.
"The purpose of American policy is not to dictate any specific outcome to cross-Strait relations. The limited aim of American strategy is to elongate the time horizon for leaders in Taipei and Beijing to explore peaceful, noncoerced solutions to cross-Strait challenges. If leaders in Taipei or Beijing abandon all hope of any peaceful solution to cross-Strait differences, then the risk will spike for one or both sides to take actions that could precipitate conflict. A war in the Taiwan Strait would constitute a failure of American statecraft."
