Communism, Islam, North Korea - Why NK develops mlitary so fast?

  Ever wondered why North Korea has gained its missile and nuclear technologies in such a skyrocketing pace?

  When North Korea was under the rule of Kim Il Sung, its founder, there was hardly any news nor military threats toward the outside world. Since his death and his son Kim Jong Il came to power in 1994, we start to hear and gain more awareness about the country little by little, but its technology and scale is still far from threatening. Since Kim Jong Un's era after 2012, especially recently, the scale, frequency of test, and level of technology has grown so large an extent that its existence makes one impossible to ignore.

  So Who is behind North Korea? The answer is: Russia (Soviet Union), China, Iran and Pakistan.
It dates back to the time when Russia was still Soviet Union. North Korea's weapons, especially nuclear ones, and technology are mainly from Soviet Union. China is another "friend" who has been supporting DPRK politically and economically for decades. Some photos expose that a part of weapons and complimentary military tools are "Made in China".

  It's not surprising that Communist countries are allied, to combat "Western forces". But how about Islamic countries? In a nutshell, their agenda is similar to Communist countries, as "anti-West". Those countries used to be moderate and much more peaceful until late 1970s and early 1980s, when fundamentalism and religious fanaticism took place. There may be other minor players, but it's widely known that Iran and Pakistan are trading weapons with DPRK, which at least provides it economical benefits. DPRK has diplomatic ties with many Islamic countries, while it doesn't recognize Israel, as many hard core Islamic countries also don't.
