mont, I congratulate you on having been to Israel, and I'm not speaking sarcastically.

Most of the posters who live on this Board have never been there, and it's very apparent in their posts (like someone who spoke of apartheid there, or the map that Kondor posts).
Outside of Europe and the U.S., I have worked/lived in Israel, Jordan, Saudi Arabia, Dubai, Syria, South Africa, India, Iraq, Nigeria and many Latin American countries. I also "lived" in Vietnam as an Lt. with the 196th Light Infantry, based at Da Nang.
I have nothing against Israel, I was involved with the supply of urgently needed munition components to an Israeli munitions plant which were certainly used against the Palestinians. Not proud of it but, it was my job. But I like to call a spade a spade so if my observations offend Israeli right or wrongers, that's ok, but they are observations of a true neutral.
