Ri Chon Jae, adviser of the South Side Headquarters of the Pan-national Alliance for Korea's Reunification, said the largest-ever nuclear war exercises that have been lasted for nearly two months with the involvement of hundreds of thousands of troops were a crime indicative of the U.S. ambition for hegemony.

Obama made confession that "a nuclear war cannot be fought on the Korean peninsula now" not because of the safety of the south Korean people but because of the north's nuclear capabilities, he said, adding:

The U.S. conclusion that a nuclear war can not be fought on the peninsula just stemmed from the present situation.

But the chief executive still keeps pursuing south-north confrontation and war moves, turning her face away from the trend of the times.

The driving force that can give spurs to change is ourselves, he said, stressing the need for all the people to have confidence that they are the masters of the times.

At the end of the lecture, there was a demonstration march to the "government" building.
