Secretary of State Hillary Clinton visited Seoul, South Korea after a three-nation Asian tour just as tensions with North Korea continue to deteriorate.
It has been one week since international investigators concluded the North was to blame for the torpedo that sank a South Korean warship and killed 46 sailors.
Dr. David Meyer, a professor at Regent University and an expert on international relations and military history, appeared on CBN Newschannel's Morning program to give his assessment of the conflict between the two countries.

"They have pursued the truth and then formulated a response," Clinton said after a meeting with South Korean officials.
Clinton pledged U.S. support for South Korea's government and its decision to end trade with North Korea.
"This was an unacceptable provocation by North Korea and the international community has a responsibility and a duty to respond," Clinton said.
But as Clinton waited for the world to respond, South Korea has taken punitive steps against the North.
South Korea has started sending propaganda broadcasts into the North after a six-year hiatus. It has also barred the North's cargo ships from its harbors.
Meanwhile, the North has responded with the same broadcasts and has threatened to destroy the South's propaganda facilities in the heavily militarized border. The communist country has also said it would close cross-border traffic between the two countries.
"Really there is the immediate crisis caused by the sinking of the naval vessel, which requires a strong but measured response," Clinton said. "But there is the longer term challenge of changing the direction of North Korea, making a convincing case to everyone in the region to work together to achieve that outcome."
China, who is North Korea's main ally, has remained neutral in the dispute so far.
"I believe that the Chinese understand the seriousness of this issue and are willing to listen to the concerns expressed by both South Korea and the United States," said Clinton, who visited China before coming to Seoul. "We expect to be working with China as we move forward in fashioning a response."
