Good observation. But to give due credit to Mr. Sen, I think this is more of an Editor's gimmick... nowhere has Mr. Sen been quoted as using the peculiar word..
Perhaps a bigger faux-pas on his part is the chest beating announcement that India is most favorable to US (re: "I've been envoy to Russia, UK, Germany.."). So is he saying that we actually despise those countries? Hasn't he made life difficult for the current envoys to those countries?.. .:-)
This is diplomacy at its best.... Congress style.. ;-)
