Clark's narrative is crisp and bracing, a concise view of Salvador Allende's life that in retrospect always seemed headed for an ultimate climax. Chile's doomed Marxist president came from the upper echelons of his society. Yet while he came from social privilege, his family was comparably not very wealthy. This duality allowed Allende to easily access institutions and levers of power while remaining steadfastly dedicated to Marxist ideals.
Allende's living context was also unique. He was only a generation or two removed from Latin America's Independence wars, in which his grandfather played a role. At the same time he came of age in the 1920s and 1930s at the peak of Soviet Communism's international prestige and influence. (Something Clark could have done more of was give readers a peek into Allende's personal views of worldwide political movements that occurred in his youth.) His easy access to politics, the times in which he lived, and of course all his personal gifts and abilities came together as a living political doctrine that can be called Allendismo.
Allendismo, as Clark describes, is the expression of Allende's belief in the Chilean Road to socialism. It involved radical but yearslong reforms of existing political and economic institutions, discarding what didn't work and keeping what did. For example he wanted to incorporate workers' unions into the organs of government, to give them a proactive role in managing the economy. In Allende's view it would have been best to avoid the devastating violence and collective trauma of a Bolshevik-style revolution and instead try to appeal to a broad coalition in the middle. Throughout the book Clark sketches Allende's road to the Chilean Road, and provides an appropriate level of detail for important figures in his life.
After two tries at the presidency he finally won in 1970. Unfortunately that's also the time when the CIA's work to undermine and destroy communist movements worldwide was in full swing. Clark's interpretation is that had the US not immediately started financing and arming the opposition, Allende could have formed that centrist alliance. It is a persuasive view.
I've never read anything like the chapter about the coup itself. I could envision it as a high production film. After waking up to news of of suspicious troop movements at 4 AM, Allende heads to La Moneda with his closest confidants, body guards, and a few loyal police officers. He radioed a call for help to the people of Chile, but in the end only 60 people were on hand to defend against the military coup. He took up arms, firing a rifle gifted to him by Fidel Castro out of the windows of the presidential palace. As war planes begin bombing the building Allende orders his remaining defenders to leave. By the time military insurrectionists enter the building, Allende has already fired a bullet through the top of his skull. The final chapters deal with Allende's legacy and vicious fallout from the coup, both of which are ongoing stories.
Throughout his life Allende tried mediating conflicts from the left and the right but in Clark's telling, he's the only person who could have pursued the Chilean Road. Could he have succeeded without meddling from the US? We'll never know, but as Allende himself said in his final broadcast, "social processes can be arrested by neither crime nor force. History is ours, and people make history."
