WASHINGTON -- North Korea is continuing their provocative behavior and Washington, D.C. is listening.
"I could see a major war happening if the North Koreans overplay their hands this time because the public South Korea, the United States and I think the whole region is fed up with this guy," said Sen. Lindsey Graham on NBC's "Meet the Press."
A scheduled trip to Capitol Hill by General James Thurman, head of U.S. Forces Korea, was pushed back this weekend.
A spokesman says quote, given the current situation, General Thurman will remain in Seoul next week as a prudent measure.
In D.C., lawmakers are now warning North Korea what will happen if they follow through on their threats of war.
"We would win if there was a -- an all-out conflict, but the fact is that North Korea could set Seoul on fire," said Sen. John McCain.
The U.S. was scheduled to test intercontinental ballistic missiles in California on Tuesday, but that test has been moved to next month. Defense officials say the test was never associated with North Korea, but they want to avoid any misperception that it was.
The White House says the delayed test does not mean the U.S. is caving to North Korean threats.
"North Korea is engaging in the kind of behavior we have seen for many, many years, provocative actions and bellicose rhetoric and the onus is on North Korea to take a step back," said Senior White House Adviser Dan Pfeiffer on "FOX News Sunday."
Others in D.C. want North Korea's neighbors to say enough is enough.
"The Chinese hold a lot of the cards here. They're by nature cautious, but they're carrying it to an extreme. It's about time they stepped up to the plate and put a little pressure on this North Korean regime," said Sen. Charles Schumer.
At the end of the week, Secretary of State John Kerry will travel to South Korea with American military leaders and members of the South Korean government. And we expect them to discuss tensions that have the whole world on edge.
