President Trump answering tough talk from North Korea with some tough tweets of his own.

FOX's Jon Decker explains:

Hours after North Korea threatened the U.S. with what it called "catastrophic consequences" for dispatching an aircraft carrier to the waters off the Korean Peninsula, the President took to Twitter to write, "North Korea is looking for trouble. If China decides to help, that would be great. If not, we will solve the problem without them!"

Tensions on the divided peninsula are high because of U.S.-South Korea war games now underway and recent ballistic missile launches by the North.

President Trump's national security adviser, H.R. McMaster, described the decision to send the carrier group to the Korean Peninsula as "prudent."
