This would come very close to world war 3 in short order. Kissinger, with Nixon’s approval, apparently told the soviets to turn their forces around from going to egypt/suez or the united states would start a nuclear war.
This incident doesn’t receive anything close to the coverage it deserves.
Israel would have executed the Sampson Option if they lost. That is nuking the enemy and taking them down with them. There are suspicions that since Russia was the major supplier of arms to the Arabs that they were also on the Sampson List. Israel of course could not defeat Russia but could inflict great damage on a few major cities.
We were very close to world wide nuclear exchange at that time. It would have been ugly, very ugly.
