You are correct about the $3.8b sent annually in military and economic aid to Israel, a figure established by a 2016 Memorandum of Understanding (MOU) and running until 2028. In full disclosure since October 2023 Israel has received an additional $17b in military aid which is not included in the chart below nor the total US output of aid for 2023. But we need to put these numbers in perspective to make an objective opinion if the aid is too much or average.
In 2023, the last year that numbers are available, the US spent $99.8b in aid to different countries With the largest being $16.6b to Ukraine.
Notably, Ukraine is in the midst of an active conflict with a numerically superior invading force. Ukraine has hundreds of thousands of soldiers engaged in a drawn-out war with a peer-quality force that is actively invading their country and trying to take their territory. They sustain hundreds of military casualties every day, and several thousand civilian casualties every month. Meanwhile, Israel completely outclasses Hamas, Iran, and all of its other regional enemies
combined as a fighting force, and they received more aid than Ukraine did in response to a single (large and horrific though it was) terrorist attack. I say that not to minimize the October 7th attack, but to point out the differences in scale. Objectively, Ukraine's situation is
far worse than that of Israel in the sense that Ukraine faces an actual existential threat. Even though Hamas
desires to wipe Israel off the planet, they utterly lack the capability to actually
do so. The number of Ukrainian civilians killed by Russia since 2022 has far outstripped the number of Israelis killed by Hamas, even if we go back decades. So yeah, unless you think that US aid to Ukraine is way too low, there's no real way to justify how much Israel gets.
Considering the importance of Israel‘s strategic location, the sharing of intelligence, and the business partnership I don’t see an average of $4b a year to be excessive since it merely accounts to 4% of total US aid output.
We get most of the same military benefits from Jordan - better in some respects, as we're able to actually base troops there (iirc, the only US "bases" in Israel are a radar station and equipment storage depots). Guess how much aid they get from us? And guess what their GDP is relative to Israel's?
Business partnerships have nothing to do with military aid or the government, so I don't know why those keep getting mentioned.
