Why is the midway islands a territory of the us?

I beleive you mean why ARE the midway islands a territory of the US. Well, from the mid 1800's to 1900, America was an imperialist nation. It was eager to expand. In addition to becoming more involved in foriegn affairs, the US sought colonies. It gained territory in the Carribean and the Pacific through the Spanish-American war. However, Midway was simply declared US territory and has been ever since. No debate, no conflict, no purchase, just it's mine because I want it to be....that's kinda how we are today. Every fight is our fight....every problem is our problem....blah blah blah....why? Because I want it to be! Well, we have a responsibility as a superpower....
