The idea of North Korea ever having access to an intercontinental missile has typically been considered a frightening, but remote, possibility. However Kim Jong Un is determined to see North Korea as a nuclear powerhouse in the world. And according to US security experts, Jong Un may be one step closer to that goal after their most recent missile test.

US officials have been closely monitoring North Korea and its leader, Kim Jong Un. An import ban was put into place in an effort to use sanctions to deter Jong Un. It is estimated that the ban takes $1 billion from the North Korea economy.

Apparently the ban is not slowing Jong Un down. Reports estimate that Jong Un could have anywhere from one nuclear warhead to 60.

The Daily Mail reported that in comparison, the US has 6,800 nuclear weapons and Russia has an estimated 7,000.

Experts suggest that if shot from a flat trajectory, a North Korean missile could hit the West Coast of the United States. The only line of defense for such an attack would be a missile defense system, which is located in Alaska.

Since 2006, North Korea has tested five nuclear weapons, and a Washington Post confidential report published Tuesday shows Jung Un’s growing hostility towards America is likely one of his driving motivations to have long-range capabilities.

“The IC [intelligence community] assesses North Korea has produced nuclear weapons for ballistic missile delivery, to include delivery by ICBM-class missiles.”

In the same report, the website says two U.S officials familiar with the document claim their information is accurate. Other publications have yet to verify the findings.

North Korean Foreign Minister Ri Yong Ho said Pyongyang promised to “teach the US a severe lesson.” According to CNN, North Korea was thought to have been in possession of 13 to 30 nuclear weapons last year.

The report will surely only further increase tensions between the two countries.
