Pentagon warns 'autocrats are watching' Ukraine invasion

STORY: Austin's remarks, delivered at a security forum in Canada, were some of his most powerful to date on Russia's nearly nine-month-old invasion. He warned of the risks of global nuclear proliferation.

"Putin's fellow autocrats are watching. And they could well conclude that getting nuclear weapons would give them a hunting license of their own. And that could drive a dangerous spiral of nuclear proliferation," Austin said.
