What does James Waterhouse highlight about Ukraine's situation in the ongoing conflict?

James Waterhouse, BBC News Correspondent, emphasizes the significant sacrifices Ukraine has made to withstand Russia's aggression. He poignantly notes that recent developments (within the last 24 hours) have put these sacrifices at risk of being for nothing. This observation highlights the precarious position Ukraine finds itself in, where despite enduring tremendous hardship and loss in its resistance against Russian forces, there's concern that these efforts could be undermined. This sentiment likely connects to the broader context of international support and the impact of political statements mentioned in the description.
