I was very nearly sent back early because I had a friend - a Command and Staff College classmate - who was an active duty member of the IDF - and one of my fellow UN officers claimed that I was an "Israeli spy".
Besides their implacable hatred of the Israelis, the UN headquarters in Cairo and Jerusalem wasted huge amounts of money through wastefulness and stupidity - most of the staff were either Norwegians/Swedes or some silly little county like Trinidad.
Thanks. This has been going on at least dince the 1970s
