After the referendum in the United Kingdom in June 2016, after the referendum decided to Brexit，The process has been tortuous for three years，Hard steps。Recent，EU leaders hold emergency summit again，Agree to extend the Brexit time from the previously agreed March 29 to October 31。This move has re -stimulated the strong voices of the Britain's "second referendum" and cancellation of Brexit，It also makes the Brexit situation become more and more confusing。Since the Tudor dynasty，Occainingism has always been a main line of British foreign policy，Affairs occurred on the ground。Under such a principle，Britain's policy for European policy is more helpless move to cater to national interests。From a historical point of view，Britain never thinks itself belongs to Europe，This also determines that it will not really belong to the European Union。

The Tudor dynasty is the formation period of the British nation country。In Henry VII、Henry VIII and Elizabeth I. Under the rule of the three generations of monarchs of Elizabeth I，Mathematics of the British national country。Occibular diplomatic ideas have developed in the framework of the nation -state，Traditional thoughts of becoming a British diplomacy。Its main performance includes: in European affairs，As long as it does not involve the fundamental interests of the UK，Try to get out of the world as much as possible，Not involved in European disputes，It mainly maintains European balance through peace diplomacy; if a strong bet365 best casino games country appears in Europe and threatens British security，will combine this strongest person with other countries; protect overseas colonies，Focusing on the maximum economic and trade benefits worldwide。In the late 19th century，The concept of "Glory (Hui) isolated" has been proposed and carried forward。Disrely、The three prime ministers of Glaston and Solzbury are the powerful promises of this policy。During this period，The expansion of the British Empire reached its peak，contradictions or cooperation between British and European powers，Basically revolved around the expansion of the empire and the security expansion of the empire。Strive for cooperation with European relations but avoid alliances，I want to obtain benefits from continental Europe，I don’t want to bear the responsibility of the alliance，It has become the basic position for Britain to deal with European continental affairs。

The powerful vulnerability of Britain in the 19th century Britain，It must rely on external resources to support its strength。So，The isolationism pursued by the United Kingdom does not mean that it does not associate with all alliances and does not cooperate，For example, in France in the Crimean War、Turkey against Russia; the establishment of the four -nation alliance to deal with the constitutional crisis of Portugal and Spain; the establishment of the British -Japan Alliance in 1902。It is this combination of non -interferenceism、"isolationism" for colonialism and hegemonism，Let the British stand on the top of the world power。The 1920s and 1930s，British appeasement policy is essentially a continuation of isolationist foreign policy，Through peace and compromise method，Make Bet365 app download yourself from warfire in Europe and other regions。European powers after World War II have become second -class countries，The world needs a more united Europe。Although the UK has the strength to play the leader of the European Union，But it chose to be outside，Instead of joining the United States' "NATO" to protect the Federal Federal Trade。As Churchill said，"We are with Europe (with)，instead of belonging to it (of)。We are with it with it together，but not absorbed by it "。So be France、When the German design of the European Communist Party to revitalize the country's economy，The British adopted a conflict and obstruction attitude。With the further weakening of British strength，The relationship with the Commonwealth and the United States has become more and more fragile，The United Kingdom realizes that it must break the fantasy of "three -ring diplomacy"，Re -put attention back to Europe。1973，Britain has to join the European Community，But this does not mean the end of isolationism。

　The British lacks a sense of identity in the European continent

In the process of integration in Europe，The United Kingdom has always maintained a state of Ruo Ruoli。Britain has never given up the efforts to maintain Europe in Europe，The leadership and dominance of European affairs to re -obtain European affairs; on the other side，British politics and the public still have strong suspicion of European emotions，worry about the prospects of joining the European Community in the UK。Only 2 years after joining the European Community，The Labor Government led by Harold Wilson held the first national referendum in history on the problem of staying in Europe.。Voting rate is 64%，Among bet365 Play online games them, 67.2%of the people choose to leave。At this time, the interests of the British and European Communists have not been fully exposed，Anti -Europe has blame the British economic recession on the United Europe's United。Remind the United Kingdom not to sacrifice its own national interests for European ideals，This will be a catastrophic development for the future development of the UK。So even if it became a member of the European Community，Britain has not fully invested in European affairs，Instead, emphasize the independence and autonomy of the nation -state，Refusing to join the Schengen Agreement and the Euro Area，Opposition to European Defense Integration，and involved in the internal affairs、Justice、Human Rights、Social affairs and other aspects have exceptional rights。In dealing with international affairs，The United Kingdom has repeatedly advertised "British and American Special Relations"，Including supporting the United States to launch the Iraq war。visible，The UK always seems to be showing that although I am in the European Union，But I don’t want to be against it。This can be said to be another expression form of isolationist diplomatic tradition。

The unique national characteristics of the UK determine its action。France experienced a jumping development full of violent bleeding revolution。Germany advocates the arrangement of the old system，Resistance to the surrounding tradition。British gradual development roads and institutional arrangements are different from other European countries' operating modes，So that it lacks a sense of recognition and belonging to the European continent from its origin，It is not like France、Germany has a long -lasting Bet365 app download belief and sense of responsibility for the United European United。From the east half of the British Islands to the world's number one colonial empire，A glorious achievement that Britain has been unable to reach in the UK。The sense of superiority from this has been deeply embedded in the minds of the British，It also allows them to maintain the traditional style of dealing with European affairs at all times。So when facing the new thing of the European Community，The UK looks cautious and conservative。What I do in the UK，Including emphasizing intergovernmental cooperation rather than united between national、Avoid undertaking new obligations as much as possible、Maximum the right to choose the British free choice，While protecting the interests of the country，It also added contradictions and gaps within the European Union。After 41 years，The conservative party government led by Cameron once again held Brexit referendum。Faced with refugees、European debt、EU，Britain chose to leave。Behind the Brexit operation is still the surge of British isolated diplomatic traditions。

　　Give up isolation and return to self -difficult choice

The United Kingdom was a brilliant century -old "Nothing Empire"，It never thinks it belongs to Europe，I don’t want to appear a powerful Europe that can compete with it;。In such an embarrassing situation，Britain changes the faces of isolationism again and again。When the European integration process meets its national interests，The United Kingdom is a positive promoter; otherwise it will become an onlooker or even obstructers。Brexit is happy or worried，Conclusion is early。On the one hand，The uncertainty of Brexit has brought a visible bet365 best casino games negative effect to Britain。Government prestige damage、Tear of public opinion、The slowdown in economic growth and the "escape" of multinational enterprises，Brexit is evolving from the initial political incident to a social crisis。London is also impacted as a global financial center。Britain must re -position its international role。On the other hand，Brexit may bring more room for development to Britain。Get rid of the EU's complicated rules and regulations，Refugees who are constantly influx、Immigration，A single market in Europe and a assistance obligation to the European economy，Britain can decide what or what does not want，It can be closer to emerging markets more freely and openly，For example, signing more trade agreements with the "Anglo Cultural Circle" and the Commonwealth countries，Reshape your own financial character。The EU has lost an important contributor to a very powerful contribution，Its international influence may be weakened，EU's survival crisis will increase。But from another perspective，May help France、Germany promotes the European Union's deeper integrated reforms。

The UK again reaches the crossroads of fate。How to go forward，Depending on how to leave Britain，and other countries in the world，Future cooperation including China。UK is inherently an isolated doctrine may accompany the always。British challenged traditional innovation achievements in history，"Big Charter"、Glory Revolution、Industrial Revolution, etc.，Let us have reason to believe，If Brexit is a choice of failure，It may introduce another beginning of victory: such as promoting British convergence and ambition to re -understand their bet365 Play online games roles; help British people find a sense of security that is lost in the process of European integration and globalization。No matter what，British can leave the European Union，But it is inseparable from Europe，More inseparable from the world。How will the UK will choose in the future，Let's wait and see。
