Vladimir Putin has warned NATO countries they risk nuclear war if they send troops to Ukraine. The Russian leader has been delivering his annual state of the nation address two weeks ahead a presidential election that he's expected to win. Little-to-no opposition stands in his way. Putin told Russians in his speech that he'd be stationing more soldiers in Russia's West, close to new NATO members Finland and Sweden.
Putin's nuclear warning came after France's president refused to rule out the possibility of Western nations sending troops to Ukraine. This was later rejected by the US and Germany.
