“We expect that the U.S. Congress will soon adopt the crucial decision to continue such vital support for Ukraine,” Zelenskyy said, after meeting for several hours with U.S. military commanders, including Gen. Christopher Cavoli, head of U.S. European Command, Gen. Darryl Williams, head of U.S. Army Europe and Africa, and Lt. Gen. Antonio Aguto Jr., who leads the security assistance coordination.

In a statement, U.S. European Command said they discussed efforts to meet Ukraine’s urgent battlefield needs and the ongoing training of Ukrainian forces. Training has been taking place in Germany and several other locations in Europe and in the United States.

According to a U.S. official, Zelenskyy also spoke to a crowd that gathered for his arrival, including some Ukrainian troops who work at the coordination center. The official spoke on condition of anonymity to provide details of the stop.

In his social media post, Zelenskyy said he stopped in Wiesbaden after his visit to Norway. “I was once again convinced of the excellent quality of U.S. military aid to Ukraine,” he said. “We critically need it for the victory!”
