USA HISTORY

Detailed explanation-1: -Why North Korea threatened Guam, the tiny U.S. territory with big military power. North Korea said it was reviewing plans to strike U.S. military targets in Guam with medium-range ballistic missiles to create “enveloping fire, ” according to state media.

Detailed explanation-2: -The declaration might come as a surprise to some mainland Americans, but North Korea has long had a hostile eye turned toward Guam, which is about 2, 100 miles away from the Korean Peninsula. The U.S., in turn, has heavily fortified Guam-in part to keep an eye on North Korea.

Detailed explanation-3: -However, there has been no indication that any attack on Guam by North Korea is imminent. In a message to the public, the governor of Guam Eddie Baza Calvo said there was currently “no threat” to the island and the Marianas archipelago, but that Guam was “prepared for any eventuality".

Detailed explanation-4: -In early August 2017, The Washington Post reported an assessment, made by the U.S. Defense Intelligence Agency in July 2017, which said that North Korea had successfully developed nuclear warheads for missiles capable of reaching the U.S. mainland (a miniaturized nuclear warhead that can fit inside its missiles).

Detailed explanation-5: -Guam faces an “evolved threat, ” as Hill put it, especially from China, in the form of increasingly advanced ballistic and cruise missiles, as well as new hypersonic weapons and even potential threats from space, which could strike simultaneously from multiple different vectors.
