The irony wasn't lost on Lee Min Bok when he spotted propaganda leaflets fluttering down in front of his home just south of the border dividing the Korean peninsula: it was airborne pamphlets flown the other way that convinced him to defect from the north more than two decades ago.
The leaflets that dropped into Lee's yard at the weekend are among nearly a million floated south by the Pyongyang regime as part of a psychological war that has intensified since North Korea conducted its fourth nuclear test early this month.
One had a pair of cartoons of a near-naked South Korean President Park Geun-hye smooching with U.S. President Barack Obama and Japanese Prime Minister Shinzo Abe. Another juxtaposed Park's portrait with a skull, calling her past proposals for improved ties with North Korea the "mad grumbles of a half corpse."
