Which political challenge does North Korea pose for East Asia?

I need help ASAP. Also, does anyone have the whole answers??

North Korea poses several political challenges for East Asia, such as:

1. Nuclear Proliferation: North Korea's nuclear weapons program is a major concern for the region, as it destabilizes the security balance in the area, threatening neighboring countries.

2. Human Rights: The North Korean regime has been accused of widespread violations of human rights, including torture, forced labor, and extrajudicial executions. This poses a significant challenge for neighboring countries, as they must balance their desire to promote human rights with their interests in maintaining diplomatic relations with North Korea.

3. Regional Stability: North Korea's provocations, such as missile tests and military exercises, create tensions in the region, which could lead to an accidental escalation of conflict.

4. Economic Development: The North Korean regime's isolationist policies limit economic development within the country, which is a drag on the rest of the region's economy.

5. Refugee Crisis: In the event of a collapse of the North Korean regime, there is a high likelihood of a mass exodus of refugees, which would pose a significant challenge for neighboring countries to manage.
