In a major shift in policy, US President Donald Trump's administration has approved its first major arms shipment to Ukraine under a new financial pact with NATO allies. The new mechanism, known as the Prioritized Ukraine Requirements List (PURL), could see up to $10 billion worth of weapons, including potentially critical air defense systems, sent to bolster Kyiv's forces. This development follows Trump's initial halt on arms deliveries after taking office and his recent threats to sanction Russia if the conflict continues. This comes amid reported frustration from Trump over his inability to curb Russia's ongoing military campaign against Ukraine.
