That’s a great question, but very difficult to answer accurately.
One example is the EU’s Horizon 2020 program, which gave a total of $450 million to Israel. The new updated version called Horizon Europe is expected to give about $1.35 billion in aid to Israel.
The reality of military aid is that it often comes in the form of a taxpayer funded discount. When Israel buys weapons from Italy, France, Germany, and especially the US, it often comes in the form of a “buy one, get one 1/2 off” type of discount. It’s a win for the buyer, it’s a win for the politicians, it’s a win for the arms manufacturers. Of course it’s a loss for the taxpayers, and especially for the people who are targeted by the weapons, but these groups do not have a seat at the negotiating table so their concerns are dismissed. If there is an accurate financial assessment of this type of aid, I am unfortunately unaware of it.
