Charles Krauthammer joined Bret Baier on "Special Report" tonight to react to North Korea test-firing another ballistic missile.

The missile - which has been assessed to be a KN-17, a former Scud missile that officials believe is being tested to one day target ships - "broke up in flight" and has been deemed a failure, two U.S. officials confirmed to Fox News.

"It seems to be a deliberate provocation by the leadership in Pyongyang," Krauthammer said.

He noted, however, that it was not an intercontinental ballistic missile that could threaten the U.S. homeland.

Krauthammer said that this latest saber-rattling will bring into focus whether or not China will cooperate with the U.S. in dealing with the growing North Korean threat.

He noted that Secretary of State Rex Tillerson made it clear in a "Special Report" interview on Thursday that the Trump administration believes China will work alongside the U.S.

"But we haven't seen a thing yet," Krauthammer said. "And this is a way for the North Koreans to try at least preliminarily to call the American bluff."
