The island of Guam

Postcard
The card shows a picture of the entire island of Guam from 13,000 feet (4000 Km) showing the Earth's horizon on a perfectly clear day.

The text on the card reads "Guam Micronesia". Here Micronesia refers to the overall region, not the country. Micronesia is a subregion of Oceania, comprising thousands of small islands in the western Pacific Ocean. Micronesia is divided politically among several sovereign countries. One of these is the Federated States of Micronesia, which is often called "Micronesia" for short and is not to be confused with the overall region.

Stamp
The postmark reads Barrigada. This is the post office located near/at the airport.

USA - North Korea Tensions | GUAM

Fresh tensions between Donald Trump and Kim Jong-un have raised fears of a devastating nuclear war between the US and North Korea.

The US military this morning released pictures of supersonic B-1B bombers flying from Guam after North Korea threatened to strike an American airbase on the remote Pacific island.

Two US Air Force B-1B jets took part in 10-hour mission over the Korean peninsula just hours before Kim Jong-un revealed his plans.

On Monday, Trump warned any threat to America would be met with "fire and fury".

A map of the Mariana Islands

Postcard

The remote islands on this postcard are part of two administrative units, Guam, a US territory, and the Northern Mariana Islands which make up a Commonwealth of the United States. The islands were named after Spanish Queen Mariana of Austria in the 17th century, when Spain started the colonization of the archipelago.

The island chain geographically consists of two subgroups, a northern group of ten volcanic main islands, all are currently uninhabited; and a southern group of five coralline limestone islands: Rota, Guam, Aguijan, Tinian and Saipan, all inhabited except Aguijan.

Guam is located in the western Pacific Ocean. It is the southernmost and largest island in the Mariana island chain and is also the largest island in Micronesia. The indigenous people of Guam are the Chamorros.

“The island of Guam, Guahan in native Chamorro, is a truely cosmopolitan community that reflects the cultures of its original Chamorro inhabitants as early as 2,000 B.C., influenced by countless European, American, Asian, Micronesian, and other people who have occupied, visited and immigrated to Guam since the 16th Century.”

Guam was colonized by Spain from 1595 – 1898. At the end of the Spanish American War the United Stated gained control over the island in 1898. In WWII it was occupied by Japan from 1941 – 1944 but the United States reclaimed it in 1944.
