"In December, North Korea launched a long-range rocket, which Washington and its allies took as a provocation.
In February, Pyongyang tested a nuclear charge, triggering international outrage, including from allies Russia and China. The United Nations increased sanctions against North Korea as a result.
South Korea reacted with emergency military drills, demonstrating cutting-edge, pinpoint weaponry. Annual joint drills between the U.S. and South Korea followed in March."
"New reports of missile movements in North Korea have triggered military counteractions by South Korea and the United States.
A U.S. official told CNN that two medium-range missiles have been loaded onto mobile launchers on the east coast of North Korea, but a second U.S. official said intelligence on that is not definitive.
South Korea's semiofficial Yonhap news agency reported the missiles were ready to launch, citing military sources in Seoul. They are probably Musudan missiles, U.S. officials said. They would have a 2,500-mile range and could threaten South Korea, Japan and Southeast Asia."

"AS diplomats ponder whether to evacuate North Korea, growing dissent has emerged among defence analysts - with some now insisting the rogue state may actually have the know-how to fire a nuclear missile."

What I find strange though is that tourism seems to be flowing in and out like everything's fine.
Are we that skeptical? This whole ordeal will likely not end in nuclear armageddon, but it's not outside the realm of possibility that N. Korea will start take aggressive measures to prove their intentions. Wars have been started over less.
