Although the House passed the bill in June, its sponsor, Rep. Chris Smith, R-N.J., convened the hearing to urge the Senate to act. Senate leaders declined to say whether they intend to bring up the bill.

“Without serious action from you and the world governments, many of these people will continue to flee their ancient homelands of Syria and Iraq ,” Shireen said.

Testifying at a House Foreign Affairs Committee hearing last week, a former Yazidi sex slave who goes by the pseudonym Shireen warned that IS’ genocidal campaign will succeed without international help. The hearing aimed to hasten congressional action on the Iraq and Syria Genocide Emergency Relief and Accountability Act , which would authorize the State Department and the US Agency for International Development (USAID) to fund faith-based entities providing humanitarian assistance to Iraqi and Syrian genocide and war crime victims rather than funnel the money through UN agencies.

Even as the Islamic State (IS) loses its last grasp on Iraq, the group’s Yazidi and Christian victims are clamoring for a boost in US support so they can rebuild their lives. They complain that ethnic minorities are having trouble accessing the $1.3 billion that the United States allocated for humanitarian aid to Iraq in 2017, and have turned to Congress for help.

Disappointed with United Nations efforts to provide humanitarian aid to Iraqi minorities, Congress is calling on the Trump administration to bypass the world body and provide assistance directly to Christians and other genocide victims.

"We hope that [the Senate] will consider our existential plight and that time is short for us and make it law soon," said Stephen Rasche, the legal counsel for the Chaldean Catholic Archdiocese of Erbil, which has supported many of the Christian refugees who have not entered UN camps.

The Senate Foreign Relations Committee marked up Smith’s bill in September, but largely merged it with the Syrian War Crimes Accountability Act, which would form a congressional study group on war crimes and human rights violations resulting from the war in Syria. As a result, the House would have to vote on the bill again for it to become law.

"There’s no ill-will here, there’s no bad faith,” Sen. Marco Rubio, R-Fla., said at a Senate Foreign Relations Committee hearing examining the issue. “The UN would say, ‘The money’s here, it’s available,’ but [Iraqi minorities] don’t come … It doesn’t seem like the UN officials … go any further than that and ask why are people not utilizing it and why are they not coming for it.”

Smith and others in Congress have harshly criticized the State Department and USAID for continuing to provide most of the aid via the UN despite a provision in 2017 spending legislation directing them to ensure greater aid accessibility for genocide victims.

“Career staff at the State Department and USAID have ignored the law and thwarted the will of the president, Congress and the people we represent,” Smith said at the hearing. “These bureaucrats have refused to direct assistance to religious and ethnic minority communities, even to enable them to survive genocide.”

The 2017 act directed that funds “be made available for humanitarian assistance for vulnerable and persecuted religious minorities, including victims of genocide designated by the secretary of state.” The State Department determined that IS committed genocide against Yazidis, Christians and other religious minorities last year.

The spending bill also directs the State Department and USAID to implement an “immediate, coordinated, and sustained response” for these groups while “[improving] access to secure locations for obtaining humanitarian and resettlement services.”

An estimated 800,000 to 1.4 million Christians lived in Iraq in 2002, but their numbers have plummeted to fewer than 250,000 as of 2016. And advocates say few Christians have returned to their homeland in the ethnically and religiously diverse Ninevah Plains since its liberation from IS earlier this year.

USAID, however, insists it is adequately providing assistance to displaced minorities.

“The United States has provided $115 million to the successful [United Nations Development Program (UNDP)] Funding Facility for Stabilization,” a USAID official told Al-Monitor. “This has resulted in 2.2 million Iraqis returning to their homes. A sizeable portion of this assistance is for minority communities.”

While the UNDP estimates that 150,000 people have returned to Christian communities in the Ninevah Plains, Rasche said, “Christians have seen the lowest rate of return among all Iraqi citizens displaced by war.” In particular, he said, only 20% of displaced Christians have returned to their homes in the Ninevah Plains.

Nina Shea, the director of the Center for Religious Freedom at the conservative Hudson Institute, attributes Christians’ low rate of return to poorly conceived UN aid programs to help Christian communities restart their lives.

“The UN with USAID comes up with a list of projects that it claims it’s doing in these … minority areas,” Shea told Al-Monitor. “We’ve gotten feedback from local minorities that actually nothing is happening or that what is happening is superficial. It’s cosmetic. It’s not the major projects that are needed like power and water for these towns.”

However, Lise Grande, the deputy special representative of the UN Assistance Mission for Iraq, said the UN works with both the Iraqi government and local religious leaders in the Ninevah Plains to provide crucial infrastructure to Christian communities such as an electric grid and roads.

Grande pointed to the fact that the UN immediately agreed to provide power generators to communities in the Ninevah Plains following a request from a Christian religious leader last week. She said that 151 of the 256 UNDP projects in the Ninevah Plains operate exclusively in predominantly Christian communities.

And while Smith’s bill could potentially prompt USAID to donate money to Christian humanitarian relief organizations, Grande noted that the UN already works with such organizations. In particular, she pointed to the fact that the World Health Organization funded the Christian aid organization Samaritan’s Purse to provide a field hospital for the Christian town of Bartella.

“In minority communities — in addition to the priorities established by the government — the UNDP responds to priorities established by the religious and local leadership,” Grande said.
