Ukraine’s almost daily long-range drone and missile strikes using domestically developed weapons have battered Russian oil facilities for months. The refineries have a combined annual production capacity of around 220 million barrels of oil, according to Ukraine, and make a vital contribution to Russia's military effort and its government revenue. Zelenskyy said he had a “good meeting” with the American president, and Trump described the meeting as a “Great Honor.” Trump said earlier this month he would grant Ukraine licenses to manufacture the Patriots it needs to counter Russia’s ballistic missiles. Zelenskyy says Ukraine is discussing joint production and technology exchange with both Lockheed Martin and Raytheon.
