Zelenskyy Calls US Aid Investment in Global Security and DemocracyWASHINGTON — Ukrainian President Volodymyr Zelenskyy wrapped up his visit to Washington Wednesday with an impassioned speech before a joint session of the U.S. Congress, saying Ukraine’s struggle “will define in what world our children and grandchildren will live.” “Against all odds, and doom and gloom scenarios,” he said, “Ukraine did not fall. Ukraine is alive and kicking.” Zelenskyy, who spoke in English for the address, thanked the United States for its military equipment and its financial support. “Your money is not charity,” he assured Congress. “It is an investment in the global security and democracy that we handle in the most responsible way.” Zelenskyy said that while Russia has an advantage in artillery, ammunition, missiles and planes, “our defense forces stand.” "Ukraine holds its lines and will never surrender,” Zelenskyy said. He ended by presenting Congress with a battle flag given to him by the Ukrainian defenders of Bakhmut, a city in eastern Ukraine where his forces have been engaged for months in heavy fighting. In return, House Speaker Nancy Pelosi gave him a U.S. flag that had flown over the U.S. Capitol Wednesday.   Earlier Wednesday, U.S. President Joe Biden welcomed Zelenskyy to the White House, his first known visit outside Ukraine since Russia launched its invasion of the country in February. The American people “have stood proudly” with Ukrainians, Biden said. “Democrats and Republicans together with our allies in Europe and Japan and other places, to make sure you have the financial, humanitarian and security assistance that is needed,” he added, noting that it has been 300 days since Russian President Vladimir Putin launched his “brutal assault on Ukraine's right to exist as a nation.” Zelenskyy extended to Biden his appreciation for the bipartisan support “from my heart, the hearts of Ukrainians, all Ukrainians.” “Thanks, from our just ordinary people to your ordinary people, Americans,” he said. Zelenskyy also gave Biden a Cross for Military Merit medal that belonged to a Ukrainian soldier, a captain of a High Mobility Artillery Rocket Systems (HIMARS) battery provided by the U.S. The soldier had asked Zelenskyy to give it to the “very brave president.” Accepting the medal, Biden said it was “undeserved, but much appreciated.” SEE ALSO: The two later held a joint press conference in which Biden reassured Zelenskyy of U.S. support. “We're going to give Ukraine what it needs to be able to defend itself, to be able to succeed, and to succeed on the battlefield,” Biden said, adding “We are staying with Ukraine as long as Ukraine is there.” Asked why not just give all the weapons capabilities that Ukraine is asking for, Biden said the United States is giving Ukraine what it needs to be able to defend itself and succeed in the battlefield. “The idea that we would give Ukraine material that is fundamentally different than what is already going there would have a prospect of breaking up NATO and breaking up the European Union and the rest of the world,” he said. Biden said he has spent “several hundred hours” with European allies to urge them to continue to support Ukraine. “They understand it fully, but they're not looking to go to war with Russia. They're not looking for a Third World War,” he said. Zelenskyy was asked if there is a way to end the war, a “just peace.” “For me as a president,” Zelenskyy said, “just peace is no compromise as to the sovereignty, freedom and territorial integrity of my country. The payback for all the damages inflicted by Russian aggression.” The trip comes as U.S. lawmakers are debating $45 billion more in emergency aid to Ukraine, which would bring the total American wartime assistance to more than $100 billion. Patriot missile defense As Zelenskyy touched down on U.S. soil, the U.S. Department of Defense announced $1.85 billion in additional security assistance for Ukraine, which includes a Patriot air defense battery and munitions, additional ammunition for HIMARS, missiles, artillery and other munitions. “This $1 billion drawdown will provide Ukraine with expanded air defense and precision-strike capabilities, as well as additional munitions and critical equipment that Ukraine is using so effectively to defend itself on the battlefield,” Secretary of State Antony Blinken said in a statement. Blinken said the United States is also announcing an additional $850 million of security assistance, bringing the total to an unprecedented $21.9 billion since the beginning of the administration. SEE ALSO: Zelenskyy has repeatedly urged the U.S. and others to provide air defense systems that could help Ukraine deal with missile and drone attacks by Russian forces that have hit cities across the country and battered its infrastructure. The senior administration official said Ukrainian forces will be trained on how to use the Patriot system in a third country, adding that the process “will take some time.” “Ukrainian soldiers are the fastest I've ever seen at learning new technology. They'll do it somewhere in Germany, or Poland, I’m imagining,” said retired commanding general, U.S. Army Europe, Ben Hodges in an interview with VOA Ukrainian. The Patriot, designed to protect a limited area is “the best in the world for its purpose,” Hodges said, “to knock down cruise missiles, and advanced aircrafts” but is “not a silver bullet.” Some information for this report came from Agence France-Presse and Reuters.
