Article may be exaggerating the possible escalation if ukraine fully looses the war. But your comment makes no sense. US is not at liberty to force the US into a decision by itself, for that europe would have accept that and it could very well brake NATO (Not even mentioning a partizan movement if Ukraine would lose). Not sure why would Russia want Ukraine to surrender a land that they were already occupying for what, eight years? This is less of a conspiracy and more of an actual possibility, no NATO country is at liberty to defy russia with their own soldiers without being attacked first. Any conflict between nuclear powers could easily escalate into nuclear war, any direct confrontation between NATO countries besides the US could still lead to that as a chain reaction.
