The fact that Europe is within ICBM range means that any NATO country that to comes to the aid of South Korea during a crisis puts them at risk of nuclear retaliation. Will any NATO countries risk nuclear retaliation to help the ROK?:
North Korea responded Wednesday to European concerns about being in the path of Pyongyang’s potentially nuclear-capable intercontinental ballistic missiles (ICBMs) by assuring the leader of Western military alliance NATO that such weapons were only intended for the U.S.
NATO chief Jens Stoltenberg said during an interview last week with Japanese newspaper Yomiuri Shimbun that “Europe has also entered the [North Korean] missile range, and NATO member states are already in danger.” North Korea’s ruling party-run Rodong Shinmun newspaper countered these claims, calling Stoltenberg’s remarks “false and groundless” because, although European states are indeed in North Korea’s missile range, Pyongyang has no intention of pulling the trigger.
“The DPRK’s ballistic rockets are for deterring the U.S. nuclear war hysterics and ensuring peace and security on the Korean peninsula and the region. They are not for threatening Europe and the world,” the commentary read, according to the official Korea Central News Agency, referring to the country’s official title: The Democratic People’s Republic of Korea.
