There's the assumption being made by the national security advisers to the Obama administration that the North Korean leadership is not suicidal, that they know they will be obliterated if they attacked the United States. But I would point that everything in South Korea and Japan is well within range of what they might want to do.

The quote "There's the assumption being made by the national security advisers to the Obama administration that the North Korean leadership is not suicidal, that they know they will be obliterated if they attacked the United States. But I would point that everything in South Korea and Japan is well within range of what they might want to do" by Oliver North addresses the potential threat posed by North Korea and its leadership. North is commenting on the assumption that North Korean leaders understand the consequences of attacking the United States—that such an action would result in their destruction. However, North counters this assumption by highlighting that South Korea and Japan, both key allies of the U.S., are within close proximity and could be vulnerable to attacks without triggering a catastrophic response from the U.S.

The core of the quote reflects the idea that North Korea's leadership might be willing to act aggressively toward its neighboring countries, such as South Korea and Japan, even if they would avoid direct confrontation with the U.S. North is drawing attention to the geopolitical risks and the complexities of assessing threats in the region. The leaders in North Korea may not be entirely deterred by the idea of obliteration if they believe their actions can be contained within their immediate sphere of influence.

Oliver North, a military analyst and political commentator, is known for his involvement in the Iran-Contra affair and his expertise in military and security matters. His statement reflects his deep understanding of international relations, especially with regard to security concerns in East Asia. North’s perspective on North Korea reveals the potential for miscalculation by both the U.S. and its allies, given the unpredictable nature of North Korea's leadership.

In essence, North’s quote highlights the delicate balance of power and the dangers of underestimating the risk posed by North Korea. While the U.S. may be safe from direct attack, the threat to nearby countries like South Korea and Japan is significant, and such aggression could have far-reaching consequences for regional stability and international security.
