Ukraine

Which Western country has send troops to the Ukrainian front?

so just choosing how to exactly limit the question changes if "help in war" was provided? what if western countries just helped with some nukes instead of only some normal rockets or whatever was sent there to help? what if western countries troops quick-changed their passports to be ukrainians instead?(guess that secret agencies already have enough passport printing capabilities,or just get them printed on demand), would that be sufficient to say no "western" troops were sent even if it were millions of soldiers "from" the west?

but living in a propagandainfested country i'ld already expect such bad manipulations to happen instantaneous.

what if western countries didn't send "troops to the front" but to the rest of the country so that invading military would have to fight western troops while ukrainian troops could concentrate on the front. would that also not be help in war by your (seemingly) position?

or the other way around: what if one would only call the directly by russian soldiers occupied area (like 1m² where they each actually stand) would that still be an invasion or just a US-style visit with US style damaging of democracy and economics? manipulating questions is a bad propaganda habit and does not prevent wars, it creates them.
