May 9, the South Koreans will elect a new President is Park Geun-Hye, who was removed from office in March on charges of bribery and abuse of office. While voters consider its decision, Pyongyang is believed to be preparing a sixth nuclear test and conducting multiple missile tests, while unpredictable, the US President Donald trump talks about the possibility of a preemptive strike. The Park administration has taken a tough stance against North Korea, but if he wins the Democratic party leader moon Jain, the policy will change. During the campaign, moon insisted on a more open approach to North Korea, who will combine talks and economic cooperation with the military and security measures. "I am confident that I will lead the diplomatic efforts with the participation of numerous parties that will lead to the complete abandonment of the North Korean nuclear programme and the establishment of relations between South and North for peace, economic cooperation and mutual prosperity," he said in April during a debate. Open communication with the North Korean regime contrasts sharply with the previous 9 years of conservative policy, which advocated a tough approach and tough sanctions as punishment for Pyongyang's implementation of nuclear weapons. The view moon is perceived by many as a return to the policy of "sunshine", the liberal governments in the period from 1998 to 2008. During the policy of "sunshine" Seoul along with Pyongyang, which led to closer relations on both sides of the border and showed that in the North Korean capital gains, the two presidents of South Korea. However, this approach ultimately failed to stop the nuclear weapons programme of North Korea. While the popularity of the moon may come from its position on reforms and the fight against corruption, his critics concentrated on his stance against Pyongyang. During this campaign, moon has developed a tiered approach to North Korea, including the expansion of a number of military programs defense, and also "the signing of the peace Treaty on the Korean Peninsula after the complete resolution of the nuclear issue" and the resumption of economic cooperation, including in tourism, joint industrial zones and assistance. Such measures have historically not been popular with conservative administrations in the United States. As a result, the moon's success may depend on the response from Washington about Pyongyang. "Hard to say" whether the administration is trump to block any new initiative from Seoul.
