Ukrainian President Volodymyr Zelensky said that "against all odds" Ukraine still stands, as he paid a defiant wartime visit to Washington to thank US leaders and "ordinary Americans" for their support in fighting off Russia's invasion and pledged there would be "no compromises" in trying to bring an end to the war. President Joe Biden and Congress responded with billions in new assistance and a pledge to help Ukraine pursue a "just peace." Zelensky received a thunderous ovation from legislators during an address at the U.S. Capitol, declaring that Ukraine "will never surrender" and warning that the stakes of the conflict were greater than just the fate of his nation — that democracy worldwide is being tested. Earlier Wednesday, Biden welcomed Zelensky to the Oval Office, saying the U.S. and Ukraine would continue to project a "united defense" as Russia wages a "brutal assault on Ukraine's right to exist as a nation." Zelensky, on his first known trip outside his country since Russia invaded in February, said he wanted to visit earlier and his visit now showed the "situation is under control, because of your support."
