Having observed a strict indifference to 172 edits for a long time, trying to avoid an edit war. I believe it will be possible to work with him on some subject. I still think that 172 is very POViewed. It's not a problem in itself but 172 is still systematically reverting edits on his work. It seems to be still very hard. I'm an amateur while 172 is a professionnal, he's a native English speaker and my skills in English. OK but I still think that it's not acceptable to write that the Khmer Rouge were US-backed for instance, even if the US administration did not actively oppose them. I invite everyone to have a look a the Cold War article.
