Via The War Files – Yesterday, North Korea purportedly tested another space rocket engine, which could be used for an intercontinental ballistic missile [ICBM], with the potential capability of reaching the US mainland. The rocket test is said to have been conducted at the Sohae Satellite Launching Station, where similar tests of the rocket technology took place on several occasions in March. Since 2006, North Korea has worked to develop nuclear technology and missiles that can strike the US mainland in the event of a war. America is located some 9,000 km (5,500 miles) away. The US and its allies in the region believe that Pyongyang will soon carry out its sixth nuclear missile test.
