Israel has a long history of facing arms embargoes. Right now the US supplies many of their weapons, but politics is making NATO nations less reliable sources of arms. The US, Italy, Spain, Canada, France, the Netherlands, etc are pushing for arms embargoes against Israel. IMO, this is probably one of the biggest existential threats to Israel since the US & French arms embargoes of the 60s and 70s.

(a)Unreliability of the Suppliers: Israel’s desire for the development of its own defence industry was reinforced by the arms embargoes imposed by the supplier states from time to time. Some of the important embargoes were: United States , Great Britain and several other countries imposed arms embargo on both the combatants during the first Arab-Israeli war in 1948; France imposed arms embargo on Israel on the eve of the Six Day War in 1967. As Israel relied almost exclusively on France both for fighter jets and heavy arms, the embargo had a tremendous psychological impact. At the same time the US too imposed an embargo on Israel. Two years after France’s 1967 arms embargo, President de Gaulle imposed another embargo in retaliation for Israel’s destruction of thirteen Lebanese commercial airliners stationed at the Beirut airport. In 1970, at the height of the “War of Attrition" with Egypt, the US held in abeyance an urgent Israeli request for arms. In July 1971, following the breakdown of negotiations conducted under the supervision of the United Nations emissary, Gunnar Jarring, the US imposed another embargo on a shipment of Phantom and Skyhawk planes that had been ordered by Israel and approved by Congress earlier that year. With the eruption of the fourth Arab Israeli war, Great Britain imposed an arms embargo on the region and refused to ship tank and tanks engines to Israel under previously signed contracts. Again in March 1975, when the US was unable to persuade Israel to pull back from the Sinai passes , the Ford Administration restricted the flow of arms and economic aid to Israel. Likewise, Israel faced similar problems in 1976, 1978, 1981 and 1983. [12]
So the question is if Israel can’t count on the US or Europe for arms, where do they turn?
Russian arms are garbage, and Israel needs a technological advantage over its enemies, many of whom are using Russian arms.
Chinese arms may not be more advanced than Russian arms yet, I’m not sure.
South Korea seems like a good source for Israel to buy arms. I doubt South Korea would have the political winds of change that the NATO nations have.
Could Israel form an alliance with India, where Israel designs the weapons and funds the manufacturing, but the manufacturing is done domestically in India? This seems like a good way for Israel to make sure they get the arms they need.
Israel only has 9 million people, I don’t think they can realistically become totally arms independent. Right now Israel is something like the 9th biggest arms exporter in the world. Its not a huge number (like 2% of global arms sales) but they have a robust domestic arms industry. But with a nation of 9 million people, you can’t be totally independent.
