North Korea has issued several threats against the United States, but they haven’t taken any steps to prepare their military to carry out those threats, President Obama’s spokesman said today.

“We haven’t seen any action to back up the rhetoric,” White House Press Secretary Jay Carney told reporters today. “We haven’t seen significant changes in the north in terms of mobilization.”

Asked if the young dictator Kim Jong-un was making the threats in order to establish his reputation at home, Carney demurred. “What that disconnect between the rhetoric and action [means], I’ll leave to the analysts to judge,” he said.

The Sun reported that “North Korean tyrant Kim Jong-un has stoked further tensions with the US – releasing disturbing footage of live-firing exercises using cut-outs of American soldiers as targets.”

The U.S. has responded to the threats by conducting military exercises with the South Koreans. Carney said the U.S. is taking “prudent” security measures.
