It would be an attack on russia. Sending troops to Ukraine to fight russians would be an act of war, they'd be the aggressor, not russia.

I have to disagree there. Whilst it’s clearly not happening regardless, sending troops to Ukraine to aide them in defending the country would not be aggression against Russia, as the troops would remain defensive in nature so long as they are only operating on Ukrainian territory. I concede that Russia would certainly spin it as aggression against Russia but this is already how they are interpreting Western arms supplies to Ukraine.

Unless The West/Nato attack Russia directly (ie invade Russia territory) then it is not aggression against Russia.
