It will much depend on NATO.  Since NATO is not sending troops.  UK and EU will not send troops too.  UK's present troops are there in Ukraine to train and not to fight.  US sent troops only to station at the EU borders.    Ukraine is not a member of NATO.

This shows that NATO, the UK and the EU do not want to have a war with Russia unless provoked.
