"This may be a Fabian strategy", referring to the Roman statesman Fabius who defeated the Carthaginian general Hannibal by avoiding frontal conflict.
Later Friday morning, President Donald Trump denounced North Korea, tweeting, "North Korea is behaving very badly".
"The United States and President Trump should respect the new democratic government", said Song, who is running Moon's campaign for the presidency. "China has done little to help!" He said the drills were aimed at using atomic weapons for a pre-emptive strike against North Korea. Secretary Tillerson will be in China this weekend to talk about that. This month China called for the North, its ally, to stop nuclear and missile tests, but also called for the us and South Korea to halt their military drills.
North Korea will be a top priority on all Tillerson's stops.
Speaking in Seoul at a joint press conference with South Korean Foreign Minister Yun Byung-se, Tillerson said Washington's policy of "strategic patience" had ended. But he has also hinted at a hawkish approach or shifting the onus nearly completely on to Beijing, which is North Korea's biggest trading partner and economic lifeline.
Their conservative critics, on the other hand, have accused them of seeking to appease North Korea and of being too close to China, which has adamantly opposed the weapons system.
Tillerson said that in coming weeks, the State Department will draft a new budget blueprint for spending in coming decades.
North Korea has accelerated its weapons development, violating multiple U.N. Security Council resolutions and appearing undeterred by tough worldwide sanctions. The North conducted two nuclear test explosions and 24 ballistic missile tests a year ago.
China earlier this month proposed a "suspension-for-suspension" in which Kim's regime halts it nuclear and missile programs in exchange for the US and South Korea canceling major military exercises. Pyongyang views this as a rehearsal for invasion. China remains North Korea's most powerful ally and dominant trading partner.
Tillerson urged China and other countries to fully implement the sanctions. The missile defense system is in the process of being deployed in the country's south.
His viewpoints could spark friction with Washington, but Moon would have no problem distancing South Korea's interests from those of the United States, said Kim, the Yonsei University professor.
Tillerson also rejected Beijing's proposal of halting the U.S. He said the allies had no intention to stand down the exercises that are defensive in nature and conducted transparently, unlike North Korean missile launches.
"That would leave North Korea with significant capabilities that would represent a true threat".
While he is delaying some of the drastic cuts the White House wanted, it is far from clear that Tillerson can prevail over Trump aides such as Steve Bannon who want to dismantle parts of the federal government and limit USA engagement with the world, said three of the current and former officials.
KELEMEN: He seemed to be alluding to food aid during a starvation in North Korea and fuel provided under a deal to freeze its nuclear program in the 1990s.
As long as the United States "unceasingly threatens force at the DPRK's door step, the DPRK will consistently conduct nuclear tests", he said.
Six-nation aid-for-disarmament talks with North Korea, which were hosted by China, have in fact been stalled since 2009.
Earlier Friday, Tillerson touched down by helicopter at Camp Bonifas, U.S. -led United Nations base about 400 meters (438 yards) from the Demilitarized Zone, a Cold War vestige created after the Korean War ended in 1953.
While touring the DMZ, he was said to have been briefed at the truce village of Panmunjom and had lunch with troops at Camp Bonifas. At one point they were only a few feet from Tillerson, with one taking either video or photos.
The former Exxon Mobil CEO is making his first trip to Asia as the top US diplomat. That could prove devastating for Seoul, where more than 20 million people live within North Korean artillery range.
