With the Russia-Ukraine war in Europe, Israel-Arab/Persian war in the middle-east, conflicts in the African continent and a potential Korean conflict and Indo-China conflict in Asia, it increasingly looks like WW3 is imminent.
Xi's lap dog N.Korea is sending soldiers to Ukraine to fight for Russia. If it is a foreplay to WW3, China has already rehearsed how to capture Vilnius from Belarus territory, it won't be a fight for just Taiwan or S.Korea, but Europe and Africa as well. It doesn't have to be nuclear though, M.A.D. still stands if Russia and China start to share their nukes, which isn't as implausible in the future.
