With all the military tensions around North Korea, war might be brewing soon unless everyone pulls out without doing a preemptive strike. North Korea transported its mid-range missile (the one and only so far) to the border with South Korea, according to the intercepted wires. The missile can strike South Korea, US forces near South Korea, or even fly further and strike Japan. The military movements by North Korea started as a response to the annual US-South Korea training exercises that were widely covered by the media.
To show how peace can suddenly turn into war, take any (non-war) painting or movie and give it a military/war theme.
