You're exactly right.
It is similar to
"Hey Israel, we are trying to save the Arab kingdoms, would you mind allowing rockets to be fired at you? Thanks, knew you would. And in return, we will rush Patriot missiles which won't work but, it shows we rush to your defense. And we really hope and pray not too many die when the Rockets land"
And then:
"Hey Israel, Kuwait is Liberated, and we owe you, so here is a the hot poker that will go up your ass unless you show up in Madrid where your surrender to the "Palestinians" begins.
LIKE FATHER LIKE SON

Israel doesn't need the US to rush to its aid. When it does, it's dead.
And if in this day and age, Israel again ever needs emergency supplies from the US as they did in 1973, it will be medical supplies to save whatever Israelis are still alive.
My guess Israelis may remember a similar Eisenhower promise. By historical accident, the obligation of enforcement fell to LBJ. I can't imagine why any nation would depend on promises for their survival. Including American promises to Israel. Not worth the bandwith they're preserved on.
