President Joe Biden has authorized Ukraine to use U.S.-given long-range missiles to strike inside Russia, a move that has raised concerns among Trump allies who believe it could lead to 'World War III.' Ukraine can now target positions in the Kursk region, where Russia has deployed troops. Biden officials feared further entrenchment in the war, but Ukrainian forces have been pleading for months to be allowed to strike inside Russia. Russian President Vladimir Putin has yet to respond to the reports, but his spokesperson accused the U.S. of adding fuel to the fire.
