My understanding from years ago was based upon my father being in WWII (42 INF), the Korean War (24th INF) , and; he was in Vietnam for two years (MACV x2). Yes, I was there also in high casuality unit, but; three wars is a tip of the beret. The deal I understood was like McCain, in that if both parents were US citizens and serving this nation overseas, every military brat born in Germany, Spain, Taipei. etc. or whatever military overseas US military hospital to two US citizens was a native born citizen. Obama does not fit this.
