You realize the date the Russians gave when they said "no really, we're dead serious now, cut off all support to Ukraine by then or we WILL use nukes" came and went like five months ago?

There is absolutely no reason to take that seriously as a possibility anymore.

When some of those North Korean "security" soldiers get killed, then you've got another nuclear power involved

....did that make more sense in your head before you said it?

does the term cannon fodder mean anything to you?

Yes and it does not improve the amount of sense you're making.
