Although William Orpen`s painting, The Signing, was a historic moment of dissolution, the historical consequences of the event would destroy the peace it was to attain. The treaty proved to be penalizing, distributed recriminations and reparations on a defeated Germany. In twenty years, its provisions have been partly responsible for a new European cataclysm. On the other hand, the GFA did not concede a victory for both parties. While there have been many regrets about the Brexit process, the almost uninterrupted respect that all parties have for the risks of tearing up this agreement has been positive. There has been much criticism of Prime Minister Johnson`s proposed withdrawal agreement with the EU, but the most imprecise is the assertion that it “drifts” a coach and horses through the provisions of the Good Friday Agreement (GFA). This assertion was made by the DUP`s parliamentary leader in Westminster, Nigel Dodds; His colleague Jeffrey Donaldson mp also argues that the draft agreement does not “adequately” reflect the CMA`s principle of approval. Since Donaldson withdrew from the Good Friday negotiations in the morning, the morning they were closed, and Dodds strongly opposed them, they may not be the most credible sources for the legal facts of this agreement. On 11 January 2020, on the basis of the New Decade Agreement, the new concept, the executive and the Power-Sharing Assembly, the Executive and the Assembly were reinstated, to the participation of the five main political parties in Northern Ireland.
14 Therefore, the GFA, as a common and reciprocal redefinition of British and Irish public sovereignty over Northern Ireland, was a remarkably incomplete and unfinished constitutional process. The withdrawal of the United Kingdom and its border problem in Ireland show that the 1998 agreement did not go far enough to provide for an explicit, indisputable and constitutional (new) definition of the Dublin and London obligations as the sovereign guarantee of the agreement. As most people understand, the proposed future management of customs, internal market regulation and VAT has been negotiated because the EU, THE UK and Ireland are trying to fully preserve the main features of the Good Friday Agreement. The most obvious assumption is that the joint membership of the United Kingdom and Ireland in the EU customs union and internal market would enable Ireland to become “borderless”. 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 agreement was reached between the British and Irish governments as well as eight northern Ireland political parties or groups. Three were representative of unionism: the Ulster Unionist Party, which had led unionism in Ulster since the early 20th century, and two small parties linked to loyalist paramilitaries, the Progressive Unionist Party (linked to the Ulster Volunteer Force (UVF) and the Ulster Democratic Party (the political wing of the Ulster Defence Association (UDA). Two of them have been widely described as nationalists: the Social Democratic and Labour Party and Sinn Féin, the Republican party affiliated with the Provisional Republican Army.   Apart from these rival traditions, there were two other assemblies, the Inter-Community Alliance Party and the Northern Ireland Women`s Coalition.
