North Korea launched scathing verbal attacks against South Korean President Park Geun-hye on Saturday, calling her unification initiatives unveiled in March in Germany "irrelevant and nonsensical."    In her "Dresden Declaration" made last month in the former East German city of the same name, Park unveiled a package of proposals calling for bolstering exchanges with the North, including Seoul's humanitarian aid projects for the impoverished North, as she pushed to end the Korean Peninsula's six-decade divide. "The Dresden Declaration is a nonsensical statement made by an anti-reunification element who deceived the public with hypocrisy and deception as she offered no solution, ignorant of the present state of the North-South relations," said a spokesman for the powerful National Defense Commission.
