Guinn does a good job of explaining the turmoil in Mexico in the first few decades of the 20th century. and how a Mexican general named José Doroteo Arango Arámbula, but who went by the name of Pancho Villa, was a key figure in it. Guinn analyzes the nature and temperament of each man in this battle of wills and does a good job of explaining the ebb and flow of power. While most men in positions of power in the goverment sided with the rich and landed aristocracy, Villa championed the poor and landless. He helped force out President Porfirio Díaz when Diaz did not do enough to promote land reform, led forces that outsted the right-wing General Victoriano Huerta, then after helping him attain the presidency, turned against Venustiano Carranza when the new president dragged his feet over promised social reforms.
Villa, who had been a supporter of the United States, changed his mind when the US continued to back Carranza.
On March 9, 1916, Villa led about 600 of his soldiers across the border and raided the town of Columbus, New Mexico, about 3 miles into American territory. There are many theories why Villa did this, but Guinn asserts that he wanted to provoke the United States Army into chasing him back across the border to prove to the Mexican people that Carranza was too weak to oppose their neighbor to the north. He expected an American invasion to lead to Carranza's overthrow.
Guinn's narrative goes beyond the Punitive Expedition. He details violence all along the border, including the frequent and bloody clashes in Texas. Guinn is particularly damning of the imperiousness of an American foreign policy that looked down on Mexico as a poor and illiterate neighbor, and of Texas Rangers who looked more like members of the Ku Klux Klan than protectors of the innocent.
I was particularly interested in what Guinn had to say about the relations between Japan and Germany during this period. I thought I knew the contents of the Zimmerman telegram fairly well but didn't know about the overtures Germany had made to Japan, including offering them California while Mexico took back the remaining border states.
I wish Guinn had said more about Villa's death, which is covered in a single sentence in the epilogue of this book. The last chapter also explains how Columbus remains divided about the Raid and its meaning even today.
