Putin would 'think twice' about using strategic nuclear weapons

Former US Army Vice Chief of Staff General Jack Keane says he doesn't think the chances of Russia using strategic nuclear weapons are very high.

"Even though they've been communicating something like that on state television," he told Sky News host Andrew Bolt.

"It's pretty outrageous, I've never seen anything quite like it - in my mind - since we've had these nuclear weapons, to have a country actually threaten the use of them like that and do it on state television.

"The United States, Britain and France - we have a significant strategic nuclear deterrence that would certainly force Russia to think twice about ever using weapons like that."
