Outright finlandising is probably unlikely, but I can imagine a situation where the West, at least for some decades, is put off intervening in any war, civil war or revolution in the Middle East (i.e. from the Tunisian border to the Gulf of Arabia, and from the Bosphorus to the Straits of Aden) after Saudi-Arabia and the other OPEC countries make the Oil Crisis vastly more severe. Not so severe that they cut off their income, but so that... the West won't pay the price anymore and where they also threaten to do this again and again any time anyone supports Israel/intervenes in the Middle East.
Of course, the West would pump truly massive amounts of money into alternative energy forms, and into nuclear plants, and by 1990, we are out of this state again. But nevertheless... nearly 20 years of not intervening in the ME will lead to at least Israel having been utterly crushed.
