US: no indication Russia plans to use nuclear weapons

The United States is watching to see if Russia’s nuclear posture changes following an armed rebellion over the weekend. Russia has the world’s largest nuclear arsenal and any political instability there is a cause for concern. John Kirby with the White House National Security Council says they’ve seen no indication that Moscow plans to use nuclear weapons inside Ukraine. And Kirby says the U-S has seen nothing to change its “strategic posture.”
