The British government is virtually out of the game and neither parliament nor the British people have, as part of this agreement, the legal right to obstruct the achievement of Irish unity if it had the consent of the people of the North and The South… 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.  Under these conditions, power-sharing proved impossible to bear. Meanwhile, voters in each community began to turn away from moderate parties, and instead support for Sinn Féin and the DUP grew, supplanting the SDLP and UUP. For much of the decade following the Good Friday agreement, decentralization was suspended because the main parties in each community were unable to reach a power-sharing agreement. Progress has been made on decommissioning, which was confirmed in September 2005, but a political agreement has remained thoughtless. Finally, the British and Irish governments held crisis talks in St Andrews in October 2006. There, Sinn Féin finally agreed to accept the PSNI, while the DUP agreed to share power with Sinn Féin.
Finally, in May 2007, a leader of the DUP, Sinn Féin, UUP and SDLP was able to take office. This time, the institutions created under the Good Friday Agreement should be maintained until the current political crisis of January 2017 has led to the collapse of the executive. In the context of political violence during the riots, the agreement forced participants to find “exclusively democratic and peaceful means to resolve political differences.” Two aspects were taken into account: the agreement called for the creation of an independent commission to audit police regulations in Northern Ireland, “including ways to promote broad community support” for these agreements. The UK government has also pledged to carry out a “large-scale review” of the criminal justice system in Northern Ireland. Both views have been recognized as legitimate. For the first time, the Irish government agreed, in a binding international agreement, that Northern Ireland was part of the United Kingdom.  The Irish Constitution has also been amended to implicitly recognize Northern Ireland as part of the sovereign territory of the United Kingdom provided that the majority of the population of the island`s two jurisdictions has agreed to a unified Ireland. On the other hand, the language of the agreement reflects a change in the UK`s emphasis on the one-for-eu law to United Ireland.
 The agreement therefore left open the question of future sovereignty over Northern Ireland.  Despite the fragility of the institutions created and the continuing bitterness between politicians representing the two communities, the Good Friday Agreement remains an important milestone in Northern Ireland`s history.
