I don't think so. I am aware that the US has thrown in about 20 Billion to the war effort. Israel has spent more than twice that much from its own budget.
Pre-war US military aid was about 4 billion/year, compared to the the Israeli domestic budget of 16 Billion/year.
The idea that Israel would have "no guns" without US aid is flat out wrong. Doubly so when you are talking about enough guns to to defy the ICC, which actually has zero.
