America financial support of Israel goes far beyond the three billion per year which is supposed to be used to buy weapons in Anerica (and is not), and the series of neverending "loan guarantees" . America also spends tax payer money to invest directly in Israeli firms. America buys all the fuel used by the IDF and has done so for decades. America steers business to Israel such as the Turkish drone deal. America stages military supplies in Israel which Israel has never bought, but are available for Israel's use "in an emergency". There are many rivers of money flowing from America to Israel. There is no way that Israel could support itself at it's present standard of living.
