First, after the establishment of the Vienna system, Britain and France formally became absolute allies.
/kloc-At the beginning of the 0/9th century, European countries jointly defeated the powerful Napoleon. The subsequent Vienna Conference defined the new European order, and the system formed by this conference was also called the Vienna system. The core of this system is Prussia and Austria, two central European countries, and France is marginalized. But then Russia began to expand into Central Europe, and the momentum was very strong. The most important thing is that Russia has good relations with Prussia and Austria at this time, so the problem comes. Britain has always advocated the policy of balancing the mainland, and it never wants Russians to dominate the European continent. Britain and France began to formally unify, which is exactly what the French want, and France returned to the center of European ruling order. /kloc-The Crimean War, which began in 0/853, was a fierce collision between Britain, France and Russia. In the end, Russia was defeated and forced to cede territory for peace. After Russia retreated to Eastern Europe, Britain and France became the absolute masters of Western Europe.
/kloc-Prussia will rise rapidly in the late 0/9th century. 187 1 year, the Franco-Prussian War broke out and France was attacked by Prussia. At this time, Britain chose to stand by, because the British thought that France's power was too strong, which was not conducive to its own mainland balance policy, and made France suffer some hardships, while the balance of national strength in the European continent was the best. However, after Prussia evolved into Germany, the country's stamina was growing. With the strengthening of national strength, Germany began to challenge the absolute authority of the British empire all over the world, which Britain absolutely could not tolerate. At the beginning of the 20th century, Britain and France joined forces again, but in order to jointly deal with Germany, they also joined forces with their old enemy Russia. The pattern of confrontation between the two camps in Europe was formally formed, and finally World War I broke out with a gunshot in 19 14. Although the Germans have strong fighting capacity, they can't resist the repeated attacks of major powers. Finally, Germany announced its surrender at 19 18.
Second, good friends will also have a big falling out in front of specific interests.
After Germany surrendered, the issue of rebuilding European order was put on the table again. The first is the weakness of Germany. Since Russia mutated into the Soviet Union, European affairs have been nothing. France advocates weakening Germany with all efforts in order to achieve the goal of France dominating the European continent. Britain wants Germany to contain France, and it is in Britain's best interest for the two countries to die. On the issue of Germany, Britain and France had a fierce contest. However, on other issues, the attitudes of the two countries are still the same. The United States has always wanted to intervene in European affairs, and Britain and France have joined forces to push the United States out of the European order circle. There is also the relationship with the Soviet Union. Britain and France have always ignored the Soviet Union, and they are totally opposed to Soviet ideology. After the rise of Nazi Germany, Britain and France were forced to negotiate with the Soviet Union, but due to the destruction of Poland, the negotiations among the three countries did not achieve any results.
1939 September, Germany dispatched1500,000 troops to attack Poland. As nominal allies of Poland, Britain and France were irrevocably forced to declare war on Germany. However, the British overestimated the combat effectiveness of the French army. Britain thought that this war would enter a positional war like World War I, so Britain was slowly assembling its troops, and Britain's surprise happened. France was completely unprepared for the German attack and surrendered to Germany within 40 days after the war. At this time, Britain is facing an embarrassing situation, and it will fight alone. In order to prevent the ships of the French navy from being used by the Germans, the British navy was ordered to attack the French navy. The two countries that wore a pair of trousers last month are at war now. The British navy issued an ultimatum to the French army: "Either join the British army or be eliminated. This is not the tone of former allies, but clearly the enemy.
Third, under the protection of the United States, European countries have become a group of good friends.
Naturally, Britain alone could not defeat Nazi Germany, but Germany attacked the Soviet Union at the wrong time, while Germany's ally Japan attacked the United States at the wrong time. In this way, the result will be different. Under the attack of Britain, the United States and the Soviet Union, Germany finally announced its unconditional surrender. After the German problem was basically solved, the two superpowers, the United States and the Soviet Union, immediately turned against each other. At this time, Britain, France and other countries have lost the ability to fight against the powerful Soviet Union independently and must rely on the power of the United States. Then two camps, NATO and Warsaw Pact, emerged. Britain and France shake hands with Germany. Now they have become a group of good friends, and their opponents are the Soviet Union. Although there are still contradictions among countries, their attitudes on diplomatic issues are basically the same. There is no friendship between countries at all, and the most important thing is national interests.
