Call me old-fashioned, but I thought our ambassadors represented the president of the United States and the dignity, gravitas and respect that office commands. It embarrasses and saddens me to see pay-to-play Ambassador to Singapore Kirk Wagar reduce the job to that of a popularity-seeking buffoon who courts attention through karaoke and then brags about it.

Al Kamen reported [“Dissenting votes from the Foreign Service?,” In the Loop, Feb. 26] that Mr. Wagar wrote on Facebook that “Singapore had never seen an Ambassador from the United States do karaoke.” Well, Singaporeans have not seen this before because no previous U.S. ambassador to Singapore has so trivialized his office.
