There is no one accepted international view on repatriation. Every country is taking an individual approach. The U.K. approach is similar to that of France, Jordan and Germany, so not unusual or especially arrogant. Here is list of the top ten countries with most ISIS members and what they are doing
Turkey: Estimated 7,476–9,476 individuals affiliated with ISIS. These are all being prosecuted and convicted in Syria and Iraq. Turkey then asks them to be transferred to Turkish prisons to serve out their sentence. “Prosecution processes of [ISIS]-affiliated women … imprisoned in Iraq have been going on for a while,” the Turkish embassy in Washington, D.C., wrote in a statement. “We have conveyed our request to relevant Iraqi authorities to transfer those convicted to Turkey to serve the rest of their sentences.”
Tunisia: Estimated 4,000–6,500 individuals affiliated with ISIS
Tunisia has not taken a public stance on repatriation. “More than 800 of [its] fighters have already returned — and quite a few of them undetected,” said Dr. Hans-Jakob Schindler, a senior director at the Geneva-based Counter Extremism Project.
Russia: Estimated 4,000–5,000 individuals affiliated with ISIS
Russia has openly called for the return of Russian children, and Russian media outlets have reported that at least 150 children had been repatriated as of February 2020. The numbers of adults who have been repatriated and have stood trial is not available.
Saudi Arabia: Estimated 3,244 individuals affiliated with ISIS
Saudi Arabia’s track record on ISIS-related repatriation is murky, said Adam Coogle, deputy director for the Middle East and North Africa at Human Rights Watch.
Jordan: Estimated 3,000–3,950 individuals affiliated with ISIS
Jordan’s official policy is to prevent “terrorists or their families” who traveled to Iraq or Syria from returning home, although ICSR estimates that about 300 Jordanians affiliated with ISIS have done so.
Uzbekistan: Estimated 1,500–2,500 individuals affiliated with ISIS
“[Central Asian countries] are pretty united with rejection of bringing men home,” said Anne Speckhard, director of the International Center for the Study of Violent Extremism. “They judge the men harshly.”
Unlike men, women are seen “as having little choice,” Speckhard said. More than 318 Uzbek citizens — all women and children — have been repatriated from Syria and Iraq over the course of three missions, according to Javlon Vakhabov, Uzbekistan’s ambassador to the U.S.
Tajikistan: Estimated 1,899–2,000 individuals affiliated with ISIS
In 2015, Tajikistan announced amnesty for ISIS fighters who returned home voluntarily, expressed remorse and renounced ties to foreign militant groups. By 2019, at least 100 citizens had accepted the offer — with mixed success. As of 2018, there were at least 30 known cases of recidivism, with Tajiks re-joining the Islamic State. Tajikistan has actively repatriated mostly women and children, largely as a way to gain more political leverage with the United States.
France: Estimated 1,910 individuals affiliated with ISIS
Although France has strict terrorism laws allowing defendants to stand trial in absentia, that practice is uncommon. The government also tends not to repatriate, according to Egmont’s Thomas Renard. The return of 10 orphans of French nationals from Syria on June 22, 2020, brought the country’s total ISIS-related repatriations to approximately 35 — all children.
Germany: Estimated 1,268 individuals affiliated with ISIS
Germany has conducted very few repatriations, according to Hannah Neumann, one of the country’s elected members of European Parliament who sits on the human rights and security committees. The Egmont Royal Institute put the total around seven as of October 2020. In December 2020, Germany repatriated three women and 12 children from Syria, bringing the total to 22. This doesn’t include an unknown number of Germans deported by Turkey.
Kazakhstan: Estimated 1,136–1,236 individuals affiliated with ISIS
Like most of Central Asia, Kazakhstan almost exclusively repatriates women and children and has received global commendation for its efforts to bring home and reintegrate Kazakh citizens — at least 700 in total, according to the Kazakh embassy in the U.S. In 2019 alone, Kazakhstan brought back an estimated 524 individuals from former ISIS territory. Of those, 33 were men, all of whom were prosecuted as ISIS fighters.Rehabilitation efforts have included giving the children of ISIS fighters Kazakh birth certificates and Kazakh names. But Helf, of the United States Institute of Peace, told FRONTLINE that children are struggling to readjust, and some women have refused to work with authorities. Meanwhile, other women have rejected the invitation to return. “Kazakhstan tried, but some people don’t want to come back,” Helf said. “But the door is open.”
