What does Timothy Snyder believe is necessary to end the war in Ukraine?

According to Timothy Snyder, ending the war requires making it harder for the aggressor (Russia) while making it easier for the defender (Ukraine). He acknowledges that while the United States has the power to end the conflict, it must implement sensible policies in the right direction rather than pressuring the defender. With American policy appearing unlikely to change course, Snyder emphasizes that this must be 'the hour of Europe.' He urges European nations to ensure Ukraine can defend itself by providing all possible economic aid immediately. This approach recognizes that ending a war requires applying pressure on the aggressor while supporting the defender's capacity to resist.
