In Britain's final plan to leave the EU, Northern Ireland will be "one country and two boundaries". Why is Northern Ireland always the pain of Britain?

After more than a year of marathon negotiations, Britain and the European Union reached an agreement on the contents of 13 "Britain's Brexit" agreement. This breakthrough means that Britain has taken a key step on the road of "Britain's withdrawal from the EU", but both Britain and the EU keep a low profile on this matter. Some people compare Britain's "Brexit" to the "divorce" between Britain and the EU. "Long-term pain is better than short-term pain" is the idea of many people who advocate Britain's withdrawal from the EU, but in practice, the "short-term pain" in hope is being dragged into "long-term pain". Not to mention that the "divorce proceedings" have lasted for more than a year, even if an agreement is reached, it is not the end of the story, but the beginning of a new round of tug-of-war.

This protracted "divorce" has recently come to an end and Britain has successfully left the European Union. At present, the specific terms of the agreement between Britain and Europe have not been announced, but public opinion believes that the border issue in Northern Ireland is still the tipping point of a new round of disputes. As we all know, the northern part of Britain is connected with the land of Ireland and the United States. Both sides are in the EU, so there are no obstacles to trade and personnel exchanges. However, once Britain leaves the European Union, it will leave the European single market and customs union. The problem of "going through customs" here has become a headache for all parties, which is why Northern Ireland will become "one country and two boundaries" in the final plan of Britain's withdrawal from the EU, which has become the pain of Britain.

Once Britain leaves the European Union, it will implement a tariff system in some territories in Northern Ireland and Ireland, and Britain's withdrawal from the EU has brought a huge financial crisis to the country. In addition, the implementation of tariffs in Northern Ireland has greatly increased the burden on Britain. The "short-term pain" of Britain's withdrawal from the EU will not be short, and it will always be imported and exported from Ireland. The implementation of tariffs will undoubtedly bring a burden to Britain. However, the financial instability of Britain's exit from the EU is inherently unstable, so the pain will not be short-lived.

British workers are worried that immigrants will take their jobs. In the process of regional integration in Europe, British workers do not have much share. Now the world economy is depressed, because of high wages, jobs will be taken away by low-paid laborers in other parts of Europe.
