IN 1954, the American government committed one of the most reprehensible acts in its history when it authorized the C.I.A. to overthrow the democratically elected leader of Guatemala, President Jacobo Arbenz. It did so secretly but later rationalized the coup on the ground that the country was about to fall into communist hands.

Guatemalan society has only recently recovered from the suffering that this intervention caused, including brutal military dictatorships and a genocidal civil war against its Indian population, which led to the deaths of an estimated 200,000 people. Only in the 1980s, when a peace process commenced, did democratic governance resume. But a silence about the Arbenz era continued.

Now, after 25 years of increasingly vibrant democratic rule, Guatemalans feel confident enough to honor the memory of their deposed leader by incorporating his achievements into the national school curriculum, naming a highway after him, and preparing an official biography. America should follow suit by owning up to its own ignoble deed and recognizing Arbenz as the genuine social progressive that he was.

Washington feared Arbenz because he tried to institute agrarian reforms that would hand over fallow land to dispossessed peasants, thereby creating a middle class in a country where 2 percent of the population owned 72 percent of the land. Unfortunately for him, most of that territory belonged to the largest landowner and most powerful body in the state: the American-owned United Fruit Company. Though Arbenz was willing to compensate United Fruit for its losses, it tried to persuade Washington that Arbenz was a crypto-communist who must be ousted.
