Each week seems to bring new heights to the tension between North and South Korea. On Monday, the South went ahead with live-fire drills, despite warnings from the North that it would retaliate. The North did not retaliate — this time — but questions remain as to when and if each side will reach its tipping point.

Kim Jong Il promoted his son to military general this past September, in the clearest sign yet that Kim Jong Un would succeed his father as leader of North Korea. What is the old man thinking?

After showing off its nuclear technology in November, North Korea fired dozens of artillery shells onto a South Korean island, Yeonpyeong, killing at least four people and triggering an exchange of fire from the South. It was the first time the North attacked the South on land since the Korean War. Here, huge plumes of smoke rise from Yeonpyeong on Nov. 23, 2010. (AFP/Getty Images)

In the wake of the North's initial attack, the region again played the parlor game of crafting a response to the regime’s idiosyncratic brand of brinksmanship. (Korea Pool/Getty Images)

The sinking of the Cheonan in March killed 46 South Korean sailors and ratcheted up tensions on the peninsula. Questions arose that, unsurprisingly, the international community is still asking today: Is North Korea ready to talk? Or, will it continue threatening to drown its enemies in a “sea of fire”?
