I seriously doubt the Ukraine situation will lead to WW3. Short of going nuclear, and Russia is not that stupid. Sure they could wreak havoc with a nuclear strike but the end result would be the obliteration of Russia and anyone involved in deciding to go nuclear hunted down and "dealt" with. Russia is to weak and has almost zero allies, so conventional war is out.

Now what the PRC does concerning Taiwan ... that could be trouble. China has been supporting various terrorist groups for years, and although not conventional forces they could cause no end of trouble inside, and for, probable PRC opponents. PRC leadership believes it would survive a nuclear exchange, and doesn't really care about their population/infrastructure, they can be replaced. Conventional warfare with the PRC would be a problem since just getting there with sufficient forces is a MAJOR issue.
