New Japanese outrage against Korea

This week's Private Eye (1135) has this clipping from the Yomiuri Shinbun:

Newsweek screwed up. Nearly everyone admits that, including the magazine's editors, who retracted an inadequately sourced report that U.S. inerrogators had flushed a Korean down the toilet at Guantanamo Bay.

I expect imminent outrage from the Korean netizen community, possibly flag burnings.
