In a post on Truth Social, Trump said that Zelenskyy could "end the war with Russia almost immediately, if he wants to, or he can continue to fight."

Russia already controls a fifth of Ukraine, including about three-quarters of Donetsk province, which it first entered in 2014.

Trump categorically ruled out Zelenskyy's desire to see Ukraine join NATO and indicated he has no desire to see Crimea returned to Ukrainian rule.
