"I think if they fire at the United States, it could escalate into war very quickly, yes".
North Korea's leader received a report from his army on its plans to fire missiles towards Guam and said he will watch the actions of the United States for a while longer before making a decision, the North's official news agency said on Tuesday.
Dunford is visiting South Korea, Japan and China after a week in which Trump declared the us military "locked and loaded" and said he was ready to unleash "fire and fury" if North Korea continued to threaten the United States.
South Korean President Moon Jae-in, meanwhile, a liberal who favors engagement with the North, urged North Korea to stop provocations and to commit to talks over its nuclear weapons program.
Calling the U.S. -South Korea military partnership "an alliance for peace", Moon said he was "confident that the U.S. will respond calmly and responsibly to the current situation".
When asked to clarify his comments on an escalation of war, Mattis said, "War is up to the president, perhaps up to Congress".
Mattis also cautioned that "we'll take it out" if the missile is located heading to the USA territory off the coast of Philippines.

They added that Dembele moving to the Catalan side is "not now likely". He added: "There was no sign that Ousmane Dembele would not be here".
U.N. Secretary-General Antonio Guterres said on Wednesday it was time to "dial down rhetoric and dial up diplomacy" on North Korea and that he had told Russia, Japan, the United States, China and North and South Korea that he was available to help broker talks.
The president added, "They will be met with fire, fury and frankly power the likes of which this world has never seen before".
Dunford on Tuesday told Fang Fenghui, chief of the People's Liberation Army's joint staff department, that the sides had "many hard issues" between them but were willing to deal with them through dialogue. "He encouraged strengthening trilateral cooperation between the U.S., (South Korea) and Japan", U.S. military spokesman Captain Darryn James said.
If "the Yankees persist in their extremely unsafe reckless actions on the Korean peninsula and in its vicinity", Kim continued, North Korea would "make an important decision as it already declared", he said. Mattis said the US would detect a missile of that nature heading towards Guam "within moments".
The DPRK stands for North Korea's official name, the Democratic People's Republic of Korea.
"Any second Korean War would have no choice but to spread into a nuclear war", it said in a commentary.
Gen. Vincent Brooks, commander of U.S. Forces Korea, said the exercises would go ahead as planned, starting August 21. "Regardless of whatever twist and turns we could experience, the North Korean nuclear program should absolutely be solved peacefully, and the (South Korean) government and the USA government don't have a different position on this". North Korean media is only reporting that Kim Jong Un has reviewed the plans and they might carry them out.
