Question

Quizplus · Accepted Answer

North Korea's limited trade and financial relations with the rest of the world make it difficult for sanctions to have a significant impact on its behavior. This is because sanctions are typically designed to put pressure on a country's economy and deprive it of resources, but North Korea already operates under severe economic constraints, so the impact of sanctions is limited. Additionally, North Korea has developed alternate channels for obtaining essential goods and fuels from other countries, such as China and Russia, further limiting the effectiveness of sanctions.
