South Korean intelligence has reported that North Korea has sent 12,000 troops, including special forces, to assist Russia in its war against Ukraine. This development could escalate the conflict and further strain relations between North Korea and the West. However, experts question the effectiveness of North Korea's involvement due to their outdated equipment and lack of battle experience. The move may also indicate a closer alliance between North Korea and Russia, as they signed a defense pact earlier this year in the midst of heightened tensions with the US and South Korea.
