Like every country, the presidential house represents not only the house where the president lives during his or her term, it also represents a landmark or a symbol that the citizens from such country will protect with their own lives to maintain the patriotism in their hearts as loyal citizens. Unlike other presidential houses, the "White House" as far as I am concern is the most popular presidential house in the world, leaders from all corners of the planet and all kinds of governments meet here for many different reasons. The United States, being the most powerful country on earth, allows other governments to holds meetings to establish agreements or solve international problems.
