WASHINGTON (AP) — Addressing the nation from the Oval Office, President Joe Biden has made his case for major U.S. backing of Ukraine and Israel in a time of war. He said Thursday night that support is “vital for America’s national security.” The speech was an opportunity for Biden to argue that the United States has an obligation to help in both places, as well as for him to lobby lawmakers for the money to do so. The administration plans to request billions of dollars for additional military assistance for Israel and Ukraine. Biden also wants more money for Taiwan’s defense and for managing migrants at the southern border with Mexico.
