President Joe Biden announced an additional aid package for Ukraine totaling $800 million on Wednesday, hours after Ukrainian President Volodymyr Zelenskyy made an impassioned plea to Congress for more help fending off Russias invasion.

Zelenskyy specifically asked the United States to close the sky over Ukraine to protect civilians who are being slaughtered by Russian airstrikes. The Biden administration has opposed the move, with the president saying it would kick off World War III.

Instead of jets or American troops, Biden said the U.S. would send 800 Stinger anti-aircraft systems, 9,000 anti-armor systems, including 2,000 Javelins, and 7,000 small arms, including grenade launchers, rifles, pistols, shotguns and machine guns for civilians to defend themselves. The White House said 20 million rounds of ammunition and 100 drones would also be shipped, along with 25,000 sets of body armor and the same number of helmets.

The new package brings the total amount of Ukrainian aid authorized this week to $1 billion, as a $200 million package was approved over the weekend.

This is a struggle that pits the appetites of an autocrat against humankinds desire to be free, Biden said from the White House. He added that he was using his presidential authority to transfer the equipment overseas from the U.S. Department of Defense.
