Can the United States cap North Korea's nuclear weapon by using the policy of benign-neglect

The United States is greatly concerned about North Korea. But why? North Korea is not in the proximity of the main land of the United States. Its ally South Korea has favored engagement with North Korea over punishment. Admittedly, the development of nuclear weapons is of great concern to the US although they cannot reach US main land yet. North Korea's actions target to get the attention of the US by any means. Knowing about North Korea's intentions, the US could approach North Korea and trying to establish normal relations. However, the unpredictability of the leadership is only one of the many concerns of the US why normalization of US-DPRK relations remains almost impossible.;North Korea takes any action necessary to gain the attention from the United States due to its failing economy, isolated status and political instability. Thus, if the US ignores North Korea, North Korea threatens with its nuclear weapons program. In the past, the US approached North Korea to reach agreements with the oppressive regime, which are later violated by North Korea. Its violation led to North Korea's further isolation. This circle of policy actions have been made several times in the past decades. The US could cut this circle if it ignores North Korea's threats with a benign-neglect policy approach. The benign-neglect policy could serve the needed purpose: non-aggressive, passive ignorance.
