8. Gerry Adams
Gerry Adams, the prominent Sinn Féin leader, faced a decade-long ban from entering the United States during the 1990s. His alleged connections to the IRA led American authorities to repeatedly refuse him entry, symbolizing the contentious nature of Irish-British relations at the time. Adams’ eventual admission in 1994, as reported by BBC News, was hailed as a breakthrough, underscoring America’s growing support for the Irish peace process.
