In a recent interview, President Joe Biden refers to Vladimir Putin as a "rational actor", whose invasion on Ukraine was "significantly miscalculated".
At a political fundraiser a week back, Biden expressed his concerns on Putin's aggression by stating that the world would face "Armageddon" if Russia started to use nuclear weapons. However, U.S. officials later clarified that there is not indication of a nuclear attack from Russia.
These comments from the president came shortly after a deadly missile barrage on key Ukrainian cities.
In a call, Biden says that he is ready to provide "advanced" equipment to meet Ukraine's needs.
