Deaths in the Peace Corps are not frequent, but they rightly call into question the program’s training processes, medical resources, and the security of volunteers.

The physician who treated Castle, Dr. Jin Gao, became the center of a report by the Corps’ inspector general about miscommunication and delayed reactions in the agency’s healthcare system that might have led to the volunteer’s death. Though the report didn’t blame the Peace Corps for the man’s death, it revealed inefficiencies and errors made by the doctor and others (including the ambulance getting lost on the way to pick up Castle) that added to concerns about volunteer welfare.

Many testimonies—positive and negative—reached reporters following the death. Chance Dorland, a volunteer in Columbia, said, “I was forced to leave my site . . . early because I was made sick by the inadequate and unprofessional medical care the Peace Corps offered its volunteers.” Nancy Tongue, founder and director of Health Justice for Peace Corps Volunteers, wrote that a sick volunteer carries the “burden of proof.” She expects volunteers who maintain a successful claim to be left “living slightly above poverty level regardless of prior earnings,” waiting months or years for proper treatment or attention.

The Peace Corps has also been criticized for failing to keep its volunteers safe. In 2007, Juan Duntugan, a Filipino woodcarver, confessed to killing Julia Campbell because she had bumped into him while he was enraged by a fight with a neighbor. The organization cannot possibly guarantee the safety of its thousands of volunteers in hundreds of countries around the world but it can better prepare them and be more transparent about the dangers they might face.

It can also offer better mental health services. During the application process, the Peace Corps might require, from a person who has a mental illness, letters from mental health professionals, clearance from a psychologist, and participation in a sort of exam. “Transition can often be one of the biggest triggers for mental health issues,” writes Ross Szabo, a former volunteer. Even in people not diagnosed with a specific mental illness, adjusting to life among strangers in another country can be massively stressful. And the pressure to succeed can make a difficult situation unmanageable. Another former volunteer, Emily Best, ended her stay in Senegal in 2012 after a year of frustration. She writes, “The onus of success seemed to be placed solely on the volunteer. If the volunteer struggles, it’s because she isn’t trying hard enough to adapt.”

Some volunteers have struggled with a lack of education after being handed a project in an unfamiliar field or with too little training. Kelli Donley returned home from her agricultural posting after only five months because, she realized, “the audacity of my arrogance in assuming that this time abroad would do Cameroon any good was apparent on Day 1.” Benjamin Clark was sent to Senegal as a 23-year-old with a graduate school degree. “I taught them a little about accounting and some basic math,” he writes, “but my real value was being one extra person to hold a shovel.” He thinks of the Peace Corps as a cultural exchange program more than an international aid group.

The loudest controversy for the Peace Corps in recent years has been their alleged mishandling of rape and sexual assault. On average, twenty-two female volunteers reported being raped or being victims of attempts between 2000 and 2009. In 2016, the percentage of women who said they’ve been sexually assaulted rose to 38%.

Danae Smith was attacked in the Dominican Republic and reported it to the Peace Corps in 2015. The Corps responded by blaming her for not doing enough to prevent it from happening. They sent her home immediately afterward. The U.S. Office of Special Counsel wants better training for host families and other in-country workers, including fellow teachers and priests, who represent a significant percentage of the attackers.

The agency is also being asked to provide much better access to victim care, including medical treatment and counseling.

The Peace Corps has drawn criticism since its inception in 1961 for its actions and intentions as an international development organization. Some think that its goal is mainly to create a positive image of the U.S. despite the country’s imperialistic military engagements. Others think of the Peace Corps, itself, as an imperialistic strategy, developing Western culture and planting American influence in impoverished regions around the world. Hayley White, a volunteer in Uganda, wrote that the Corps should work more closely with in-country social entrepreneurs than with nongovernmental organizations that are “often too indoctrinated in Western ideas of how things must be done.”

It is difficult to separate imperialism from a foreign aid program such as the Peace Corps or WorldTeach. After all, how can a U.S. citizen, perhaps only recently graduated from college, and maybe on their first trip outside of the country, provide meaningful help to a foreign community based on any other system than the American one in which they grew up? Instead of ending the imperialism argument outright, this is a question that is worth answering as a step toward a solution.

This article has focused on the controversies that surround the Peace Corps not to debase the organization’s mission, but because without the constant discussion of weaknesses and the incessant push to do better, these dangers will remain. Many volunteers who write about their unsatisfactory experiences maintain that the organization needs revision to do its work better, not to cease working altogether. The mission of the Peace Corps is important; therefore, it is important to ensure that its mission is carried out correctly and with care.
