UK and US special relationship

I found this lecture to be very interesting compared to other lectures because we haven't heard any information about the UK dealing with other countries except for during war times. The "special relationship" started in 1945, with the Yalta Peace Conference. It created the closest Alliance of World War II including Russia, UK, and US with Stalin, Churchill, and Roosevelt. Other special relationships between the two countries included Reagen and Thatcher, Tony Blair and Clinton and also George Bush.
When it comes to both of these countries, there are many things in common. Apart from the fact that there isn't a language barrier between the countries, they also have similar views when it comes to investments and economics, military intelligence, and legal system. When it comes to entertainment, the countries are very similar with literature, films, and theater. In the UK, London is very into theater and has various productions going throughout the year, which brings in a lot of money. The US isn't as big as the UK, but New York and Los Angeles also have various theater productions throughout the year which brings in a good amount of money as well. The fact that the countries have these things in common, among with others, I think that also made the special relationship easy.
Today, the use of "special relationship" is no longer politically correct. Some people say that the special relationship between the two countries has completely ended due to the relationship between Barack Obama and Gordon Brown. It is thought that Obama is less sentimental about the relationship and is concentrating on building relationships with other countries.
With that said, I feel that the US should still try to keep a strong relationship with the UK because of everything the countries have been through. There is always a chance that something will happen and each country will need the support of the other.
