Another entry in the growing canon of Books About Afghanistan. This one is an excellent overview of the war that doesn't get bogged down in the tactics (which are important but perhaps not the most relevant when trying to assess what went wrong and how from a higher level.) Saikal notes the weakness of the Bush administration's "light footprint " plan and frankly its duplicity (he doesn't use that word but he goes cast doubt on whether the Bush administration ever had any real intentions in Afghanistan other than to use it to legitimize its wider foreign policy goals). He includes not one but two chapters titled "Dysfunctional Governance" for the administrations of Karzai and Ghani; and chapters on state-building failures and strategic blunders.
Ultimately, you lose a war by losing sight of the mission and never committing to it in the first place, by ignoring the political context and engaging in rank hypocrisy.
Work read, naturally. My interview with the author will be out eventually. The content of the book might not surprise anyone who has paid attention, but it really lays it out in a concise and digestible format without eschewing nuance. The historical context chapter is something I wish the Bush/Obama/Trump/Biden administrations had read before ya know, marching off to war.
