Secretary of State Antony Blinken says the U.S. is planning "things that we have not done in the past" if Russia invades Ukraine. His comments follow days of diplomatic talks and a deadlock on resolving the crisis brewing along the Ukraine-Russia border, where Russia has massed 100,000 troops with tanks and artillery.
Blinken speaks to NPR's Mary Louise Kelly about the current tensions and this week's diplomatic efforts.
