North Korea threatened on Thursday to test a hydrogen bomb in the Pacific Ocean, a provocation that Lt. Col. Michael Waltz (Ret.) said could be the "final straw" that motivates China and the international community to demand regime change.

On "Fox & Friends Weekend," Waltz explained that such a bomb test would demonstrate North Korean dictator Kim Jong Un's ability to load and miniaturize a fully functional nuclear warhead onto an intercontinental ballistic missile.

He said the U.S. needs to work with China, because they have the ability to choke North Korea economically. He noted that China took a step toward that earlier this week when they told their banking system to clamp down on the regime.

"But now they have to follow through," Waltz said. "China has a history and a habit of dialing things up when international pressure dials up. And then when we shift away or attention diverts, then they go back to their same old ways."

Griff Jenkins asked if a hydrogen bomb test is the "red line."

"I think that would be unprecedented," Waltz said, noting that no nation has tested such a bomb since China did in the 1980s.

He said it would be "so hugely provocative" that it could change the calculus in the region and lead to China and the international community seeing North Korea as a threat to the world, not just the U.S. and U.S. allies.
