When President Volodymyr Zelenskyy of Ukraine set off for the United States this week on a high-stakes diplomatic mission, he had one goal above all others: rekindle a sense of urgency among his allies about Kyiv¡¯s fortunes as the war with Russia heads into what promises to be another brutal winter.
