While Trump`s support for a hard Brexit and his general disregard for liberal internationalism do not cause little concern for the peace process, it is not the majority opinion in Washington. In October 2019, a resolution was tabled in the U.S. House of Representatives to reaffirm its support for the Good Friday Agreement. She was supported by Democratic Congressman Thomas Suozzi and Republican Congressman Peter King. In November 2019, Parliament voted unanimously in favour of the resolution. The main themes addressed by Sunningdale and dealt with in the Belfast Agreement are the principle of self-determination, the recognition of the two national identities, intergovernmental cooperation between the British and Ireland and legal procedures for compulsory power-sharing, such as inter-community voting and the D`Hondt system for appointing ministers to the executive.   Former IRA member and journalist Tommy McKearney says the main difference is the British government`s intention to negotiate a comprehensive agreement including the IRA and the most intransigent unionists.  With regard to the right to self-determination, two qualifications are recorded by the writer Austen Morgan. First, the transfer of territory from one state to another must be done through an international agreement between the British and Irish governments. Second, the population of Northern Ireland can no longer be alone in united Ireland; They need not only the Irish government, but also the people of their neighbouring country, Ireland, to support unity. Mr Morgan also pointed out that, unlike the Irish Act 1949 and the Northern Ireland Constitution Act 1973, drawn up under Sunningdale, the 1998 agreement and the resulting British legislation explicitly provide for the possibility of a unified Ireland.  While last month`s withdrawal agreement between the European Union and Britain “looks very promising for Northern Ireland,” he notes that the divisions in British politics are very promising ahead of the general election on 12 December. As part of the agreement, the British Parliament repealed the Government of Ireland Act 1920 (which had founded Northern Ireland, divided Ireland and asserted territorial right to the whole of Ireland) and the people of the Republic of Ireland amended Articles 2 and 3 of the Irish Constitution, which asserted a territorial right to Northern Ireland.
While U.S. support for the Good Friday agreement is largely bipartisan, there is also a lot of politicization that underlies Pelosi`s remarks. They reflect not only the obligation to protect the agreement, but also the complex interactions of political and diplomatic actors activated by Brexit on both sides of the Atlantic. The agreement came after many years of complex discussions, proposals and compromises. A lot of people have made a great contribution. Tony Blair and Bertie Ahern were the leaders of the United Kingdom and the Republic of Ireland at the time. The presidency was chaired by U.S. Special Envoy George Mitchell.  The British government is virtually out of the game and neither Parliament nor the British people have the legal right, as part of this agreement, to obstruct the achievement of Irish unity if it had the approval of the north and south people… Our nation is and will remain a nation of 32 circles.
Antrim and Down are and will remain a part of Ireland, just like any southern county.  Nancy Pelosi, a spokeswoman for the U.S. House of Representatives, issued a series of warnings from senior U.S. officials that the British government should not reverse the Brexit withdrawal agreement it signed with the European Union.
