War between Russia, America and Europe over Ukraine?

Will Russia try to invade Ukraine, as many suggest? Would America and Europe attempt to stop such an invasion with military measures? What did the phone call on December7 between Presidents Putin and Biden accomplish? Could Germany be persuaded to cut off the Nord Stream 2 pipeline if Russia invaded Ukraine? Does the Bible say anything about a future war between Russia, America and Europe, and if so, what Ukraine’s role would be?
