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. Ambassador to NATO, said during a visit to Ukraine earlier this week: “From reconnaissance and logistics to precision strikes, Ukraine has shown the world how unmanned systems can give smaller forces a decisive edge.”
