We shall have to dig deeper, Roch!
OK, this is what it says, Roch....
Israel and Iran first fell out in 1979 following the Islamic[Iranian] revolution.
Before that the two countries had been close allies for decades, Iran was even among the first middle east countries to recognize Israel as a state in 1950.
The two countries maintained strong ties in the likes of trade, oil, intelligence, military cooperation, and technology, they had shared interests and were aligned with western powers during the cold war.
Israel even had an embassy in Tehran and there was direct flights between the two countries.
After the 1979 revolution in Iran all official diplomatic, economic and other ties with Israel were broken almost immediately. The Israeli embassy was closed in Tehran and handed over to the PLO [Palestinian Liberation Organization].
Iran immediately became anti-Israel and anti Zionist, describing Israel as an outpost of western imperialism.
And then in the mid 80's Iran started supporting Hezbollah in the Lebanon, etc,.
So, thats what it says, Roch!
Why the absolute turn around after the 1979 revolution???
Is the clue in the official description, 'ISLAMIC REVOLUTION'??
Anyway, as far as I can see nothing changed in Israel in 1979???
Seems to me the radical Theocratic regime which were voted in have certainly been to blame for most of the trouble since?
Seems clear to me, Iran waged war[for mainly religious reasons??? Partly so??] on Israel with terrorist groups within Israels neighbouring countries.
What do you think, Roch? Am I wrong?
