I understand these concerns. I would simply respond with one anecdote.
I was talking to a Swedish counterpart about the Nordic experience in Mali, and he said that initially they had gone in feeling very arrogant toward the non-western troops because they don't meet all NATO standards. He said that by the end, a lot of respect had emerged and it was actually the Swedes who recognized that troops—I think they were Mauritanian, although I'm not sure of that—alongside them had a vastly better understanding of what was going on and vastly better local intelligence because of their cultural affinity with the Malians.
We have a lot to teach the UN, but I think we also sometimes have something to learn from people we're not used to serving alongside.
