I have a couple of mates, one Scottish and one Austrian, (both now Australian), who were members of the Israeli special forces, and fought in Vietnam as part of an Israeli assassination squad attached to the US forces.
I know this for a fact, I've seen ample proof, and have also spoken about it to an Israeli mate of theirs, also there, who visited Australia recently.
However, search as I may, I can find no mention of this on the web.
Is this information too sensitive?
This to me is on par with the fact that US special forces were in Afghanistan prior to the Russian invasion, and was one of the main reasons the Russians invaded.
