If you think it is important to your position, I recommend you look into confirming those numbers.
Israel is spending around 30 Billion/yr now
US is currently giving them about 18 Billion/yr
US historically gave them about 4 Billion/yr
US spending during the war is about 75% as much as internal spending, not 75% of the total.
If US turned off the money tap, Israel would go from winning several wars at once to having to pick its fights.
