Ukraine is doing a very good job in stopping this very large Russian army. It is defending bravely. It's not a good thing for Russia, it was supposed to be quick, but the war has been going on for three and a half years and continues,” Trump said.Trump also stated that NATO countries in Europe should shoot down Russian military aircraft that enter their airspace.“Yes, I do,” Trump said when posed a question. Later, he stopped short of saying the United States would join in the effort to shoot down violating Russian aircraft.“Depends on the circumstance,” he said. “But you know, we’re very strong toward NATO.”Zelenskyy reaffirmed that Ukraine will continue to defend itself until Russia “stops this war.”On September 23, U.S. President Donald Trump said at the UN General Assembly that NATO countries buying Russian oil and gas must stop their purchases.
