British troops were withdrawn and replaced by a 4,000-strong Arab League force, which acted as a barrier against the Iraqi threat. In December 1961, Qasim's government passed Public Law 80, which restricted the partially American-controlled Iraq Petroleum Company (IPC)'s concessionary holding to those areas in which oil was actually being produced, effectively expropriating 99.5% of the IPC concession. U.S. officials were alarmed by the expropriation as well as the recent Soviet veto of an Egyptian-sponsored UN resolution requesting the admittance of Kuwait as UN member state, which they believed were connected. Senior National Security Council adviser Robert Komer worried that if the IPC ceased production in response, Qasim might "grab Kuwait" (thus achieving a "stranglehold" on Middle Eastern oil production) or "throw himself into Russian arms". Komer also made note of widespread rumors that a nationalist coup against Qasim could be imminent, and had the potential to "get Iraq back on [a] more neutral keel". In April 1962, the State Department issued new guidelines on Iraq that were intended to increase American influence there. Meanwhile, Kennedy instructed the CIA—under the direction of Archibald Bulloch Roosevelt Jr.—to begin making preparations for a military coup against Qasim. The anti-imperialist and anti-communist Iraqi Ba'ath Party overthrew and executed Qasim in a violent coup on February 8, 1963. While there have been persistent rumors that the CIA orchestrated the coup, declassified documents and the testimony of former CIA officers indicate that there was no direct American involvement, although the CIA was actively seeking a suitable replacement for Qasim within the Iraqi military and had been informed of an earlier Ba'athist coup plot. The Kennedy administration was pleased with the outcome and ultimately approved a $55-million arms deal for Iraq. Ireland During his four-day visit to his ancestral home of Ireland beginning on June 26, 1963, Kennedy accepted a grant of armorial bearings from the Chief Herald of Ireland, received honorary degrees from the National University of Ireland and Trinity College Dublin, attended a State Dinner in Dublin, and was conferred with the freedom of the towns and cities of Wexford, Cork, Dublin, Galway, and Limerick. He visited the cottage at Dunganstown, near New Ross, County Wexford, where his ancestors had lived before emigrating to America. Kennedy also was the first foreign leader to address the Houses of the Oireachtas, the Irish parliament. Kennedy later told aides that the trip was the best four days
