Things are heating up in Korea again. While a crisis on the peninsula is nothing new two things are different this time.
1) The North has used the heaviest artillery that's been fired since the end of the Korean War
2) The South has fired back and has responded to the North's usual threats and bellicose language with their own aggressive words marking a difference between the current right wing government and the Sunshine Policy of Kim Dae Jung and his immediate successors.
