Firstly, this being Valentine's day, and the "world politics" categorizer not appearing on the off topic forum group, I was expecting an ENTIRELY different thread....
Came expecting a discussion about penis sizes, left disappointed.
Don't need to tell you where you can find those.....



But in a sense, it is about "size":

I believe is in direct response to China trying to strongarm its way in SE Asia. In such a situation China just needs reasons to condemn Japan, to try and show them down in the international community.
Japan is turning into their bugbear. It is a convenient distraction and supports expansionist policies.
I think proximity has much to do with it, as well as Japan's long-held view that SE Asia was their "neck of the woods" {...the SE Asian Co-Prosperity Sphere of WWII vintage, anyone}

Racism is a factor...Japan long considered the Chinese and Koreans as inferiors...

japan's atrocities were arguably greater than nazi germany's
Notsure this is the case. The Japanese certainly made no bones about what they did...the Germans were more secretive and the true extent of the Holocaust was not revealed until the wars' end. The Allies certainly had their share...the fire-bombing of Japanese cities, Dresden, the "Bombs"...{all well debated topics, but not here, please}

Because of this the japanese, thier politicians and media in particular, have a disconserting habit of glossing over thier war atrocities, or even glorifying it, which understandably does little good for thier post war relations.
Could you give examples of this? as I am not aware of any Japanese habit for glossing over events like Nanking, Bataan, Manila, etc.....
