The U.S. Army base on Kwajalein, left, part of the Ronald Reagan Ballistic Missile Defense Test Site, is seen from the air over the Marshall Islands on June 12, 2012. The U.S. base has been used since 1946 as a staging ground for nuclear bomb tests conducted at Bikini Atoll and then as a range for inter-continental ballistic tests. Around one-thousand American defense contractors and U.S. military soldiers live on Kwajalein. The fourth island from the left is named Ebeye, and it is home to over 12,000 Marshallese people, living in an area of only 36 hectares of dry land. The Marshallese living here were pushed off many other islands to make room for U.S. missile and bomb testing activities.
