Obama's new Security appointments

First we have Chuck Hagel for defense.  He is at least a Viet Nam veteran with combat experience.  That's a good thing.  The Wall St Journal  is unimpressed, citing a number of opportunistic votes  Hagel cast back in the day. 
   Then we have John Kerry for defense.  Kerry went to Viet Nam as a junior Navy officer about the same time I was over there.  I served the regular one year tour.  Kerry managed to get home after only 8 months in country.  He  must have been some kind of jerk.  Years later when he ran for president, men who had served with him were still mad enough to form the Swift Boat Veterans lobby and torpedo Mr Kerry. 
  And finally we have this guy John Brennan for CIA.  That's a new name to me.  He spent twenty years at CIA doing this and that,  did some outside consulting, and finally joined Obama's campaign in 2008.  I know little about him, but I'm suspicious of old CIA hands.  CIA is a snake pit of  intelligence agents who want to make policy, they made major mistakes, and spend much of their time attempting the destabilize Republican administrations.  Not a good background.  Certainly not a man to clean house at CIA.
