      South Korea's president, Lee Myung Bak said sunday that Korea must seek unification with North Korea at any time and he stresses the need to end Pyonyang's nuclear programs. He states that any sacrifice will bring unification as to boost the Korean people, which eliminating the nuclear system will allows the Koreans to interact with eachother. "The existence of nuclear weapons on the Korean Peninsula would delay unification. If we are unified with nuclear weapons in possession, neighboring countries won't easily accept it," Lee said.
I believe that the president Lee has stated a false opinion. It will take Koreans to be one another in about 50 years, because no one talks about any sort of unification among South Korean citizens that seriously and no one does any physical protest like the remark in Berlin.
