Dear Ali Saadi Abdulzahra Jubeir, in a nutshell: Israel's armed wing. Because the current Israeli and US governments have embraced the law of the jungle.
For Israel, the US is the most important ally. For the US, Israel has been a key ally in the Middle East since the founding of Israel. The US is the patron of Israel. One of the reasons is second World War and the Holocaust.
In the 12-day war, the US was an important support for Israel, the US supplied Israel with weapons, helped shoot down rockets.
The USA and Israel not only have shared historical and cultural ties but also have economic and innovative ties. For instance, Israel has a prominent tech and innovative hub, and US-Israel trade includes military, medical technology and cybersecurity. U.S. military aid to Israel is also tied to the U.S. defence industry, which benefits tremendously from arms sales and joint development projects.
