Comedian 'not sorry' for Pearl Harbor joke on NBC's New Year's Eve

I read the joke.  I thought it witty and saw no offence in it.  I doubt any of the people who were offended were involved in Pearl Harbor.  I am a war vet with two tours of duty in a war zone to my credit and I am also old.  It wasn't a joke about war or the people who fought in that war.  To tell the truth, if I had thought of it I would have said it myself.
