Current standing in the UN
As the second most valuable asset in the UN due to its general neutrality in most wars it oversees all negotiations between countries. Its army is a massive deterrent to anyone who dares to break UN laws. Its nuclear arsenal is possibly the largest in the eastern hemisphere which causes even America to back off.
Value of England
Its value comes mainly from the power of the British Pound and its heavy devaluing of the petrodollar. The British Pound provides much stability to the UN through its nearly unchanging value. It also protects the value of the euro which, keeps investors on their toes and in turn makes the European Union a very interesting place but still stable enough for it to prosper. Even the smaller countries in europe use the pound often due to its high value.
