President Joe Biden is set to embark on a four-day trip to Northern Ireland and the Republic of Ireland this week to mark the 25th anniversary of the Good Friday Agreement. The trip is part homecoming, part statecraft and part politics, as Biden has a deeply felt personal history with the country. He will deliver remarks at Ulster University to highlight the progress since the signing of the peace agreement in 1998 and trace his family history in the country. Biden's trip is an intersection of his personal history and his view of international relations, and is expected to be a meaningful and memorable journey.
