You really are clueless and have over estimate Israels depends on the US. Israel is a powerhouse in the middle east. In conventional warfare Israel would own the land and air. Their fighting force is highly trained and educated and will not throw down their guns and run like the Iraqis, Iranians, Syrians, Turks and Egyptians. It's in the vital interest of the US to stay friendly and close with Israel in order to keep them in check and keep the oil flowing uninterrupted from the Arab nations.
If the IDF was to abandon their main doctrine of defense on the strategic level, no territorial ambitions, Desire to avoid war by political means, a credible deterrent posture, preventing escalation and low casualty ratio, there would be nothing stopping them (bar the US) from wiping out the military command structure of every single one of them. The IDF would even give the US military a real challenge.
Israel does not need the US as much as you thing they do. In fact the US may need Israel more. I can tell you that the US ground intelligent is piss poor in the middle east and we would be deaf and blind if not for the Mossad.
