Will Russia's war against Ukraine go global? Enter the North Koreans

Seoul is certainly taking the threat seriously, having dispatched its defence minister to Washington amid reports of a South Korean delegation expected in Kyiv. Is this the moment that NATO lifts restrictions on the use of its weaponry by Ukraine? How far will this escalation go?

And what's in it for Pyongyang's regime? In recent months, it has severed mediation channels and destroyed roads across the demilitarised zone. Those garbage-filled balloons launched toward the South may seem comical from afar, but rising tensions are no laughing matter. Does Kim Jong Un actually want war? If so, why? And is the West prepared?
