North Korea is at it Again!!!

Surfing the internet with my mighty mouse I found an interesting article titled "US research; Hundreds of NKorea missiles threaten Asia," by Matthew Pennington. this article says that North Korea can be a threat to the United States of America if it can get its hands on technology needed to guide the missiles to the US. The United States of America also says that North Korea will be fully nuclear on 2020. But, this of course is an estimate what if it goes nuclear sooner then what. I feel like they are slowly trying to sell us this war. In a couple of years we will be invading North Korea. Iran should not be concern to the United States of America because they are not conducting atomic test explosions like the North Koreans are. The US has put missiles radars in Japan just in case if any missile wants to go toward the US and the United State of America plans on putting defense systems in South Korea. The US's greatest concern is a long range missile called KN-08 this missile can be launched from any road at anytime. North Korea is developing nuclear weapons what does it plan to do with it. If they attack any country they will be invaded by the UN. I feel like this is just a dumb cause for North Korea they should just stay low key. As soon as they develop nuclear war heads the US, China, South Korea, Europe, and Russia will go in to disarm this country.
