the immigration judge, concluding that McMullen had not shown sufficient likelihood of persecution. We grant McMullen’s petition for review on the ground that the Board’s decision was not supported by substantial evidence.
II. Factual Background
The following facts are substantially undisputed: McMullen was born in Northern Ireland and reared in Great Britain. He is a Catholic of Irish descent, but he was not politically or emotionally involved with the Irish independence movement during his youth in Great Britain. He joined the British Army and eventually entered a paratrooper unit. McMullen was sent to Northern Ireland in 1969 as part of British peacekeeping efforts.
During the 1960’s, the Catholic minority in British-controlled Northern Ireland became increasingly vocal in its civil rights claims. The Irish republican movement called for independence from Great Britain and unification of Northern Ireland and the southern Republic of Ireland.
McMullen began to feel that the British Army was anti-Catholic. He claims that he became personally aware of army torture of prisoners and of army plans to use armed force against unarmed civilian demonstrators in order to provoke and draw out an underground group, the PIRA.
The PIRA, or the Provisional Irish Republican Army, is an off-shoot of the paramilitary Irish Republican Army (IRA). These groups arose out of the republican movement. They are not officially supported by any government. They purport to protect the Catholic population from the British Army, and to work, with violence if necessary, toward the unification and independence of Ireland. The PIRA, also referred to as the “provisionals,” formed in protest to the perceived inefficacy of the IRA.
When McMullen learned of the Army’s plan to confront civilian demonstrators, he deserted the British Army and joined the PIRA. He participated in a bombing of army barracks, and became well known for his attempts to forestall the attack against the demonstrators. The confrontation in fact took place, and 13 civilians were killed in what became known as Bloody Sunday.
McMullen participated actively in PIRA operations until the group became, in his view, extremist, terroristic and out of touch with the civilian populace. In September of 1974, he formally resigned from the PIRA. The following month, McMullen was arrested by the Garda, or Republic of Ireland police, in connection with his past PIRA activities. He was imprisoned for three years, during which time he was held in the maverick wing, segregated from PIRAmember prisoners.
Upon his release in 1977, McMullen was asked to help the PIRA, but he declined to assist them. After repeated PIRA intimidation, including an incident in which he claims he was kidnapped at his place of employment and driven to a remote area, McMullen agreed to help. He occasionally housed PIRA members in his home and made trips to the United States, apparently to obtain guns. But when the PIRA ordered McMullen to plan and execute the kidnapping of an American bar owner, he refused. A PIRA court of inquiry reviewed McMullen’s conduct, and, McMullen testified, a friend warned him that he would be murdered for his disobedience. McMullen then fled to the United States, using an assumed name to obtain a visa. When he arrived, he contacted the Bureau of Alcohol, Tobacco & Firearms, hoping to obtain asylum in exchange for sharing his knowledge of PIRA activities. He cooperated with the Bureau and with Scotland Yard investigators in the United States.
The INS then brought deportation proceedings against McMullen. McMullen testified at the proceedings, explaining that the PIRA was aware of his cooperation with authorities, and that he was considered a traitor who should be executed. McMullen submitted over 100 pages of exhibits consisting of newspaper and magazine articles, scholarly reports, and other publications documenting PIRA terrorist activities.
