"The lack of resistance from Chinese troops and civilians in Nanking meant that the Japanese soldiers were free to divide up the city's valuables as they saw fit. This resulted in the widespread looting and burglary."
The two comments are not even slightly contradictory. The Japanese soldiers in Nanking had been subjected to decades of master race propaganda. The Chinese were treacherous subhumans that deserved whatever happened to them. The Japs most certainly did not view the Chinese as "their community."
They are contradictory in the sense that the previous poster was trying to imply that Japanese are so well behaved that they don't even have a word for looting.
Obviously I had observed that in the example I offered, they were looting another "community".
