National security adviser Lt. Gen. H.R. McMaster said Sunday the situation with North Korea "is coming to a head."
McMaster indicated that the U.S. isn't currently considering military action in response to North Korea's latest failed ballistic missile test.
"It's time for us to undertake all actions we can, short of a military option, to try to resolve this peacefully," McMaster said on ABC's "This Week" program. "We are working together with our allies and partners and with the Chinese leadership to develop a range of options."
The Trump administration has been focusing its strategy on tougher economic sanctions, but if that fails the president will be faced with the same challenge as many of his predecessors.
He will have to determine whether economic sanctions, covert action, diplomatic negotiations or military force is the right option, according to Reuters.
A top-ranking U.S. military official told ABC's Martha Raddatz Sunday that the biggest concern in the meantime is that North Korean leader Kim Jong Un will "miscalculate" his chances of successfully taking on the U.S. and South Korea.
