Continuous relationship since 1948 — Recognition, eleven minutes after independence
The United States recognized Israel on May 14, 1948, the day it was proclaimed. Everything else on this page — the aid, the nuclear understanding, the ruptures — sits on that decision, and the shape of the relationship was set not in 1948 but in the fifteen years after 1962, when it moved from arms-length to structural.
The relationship is usually described as an alliance. In law it is not one: there is no mutual-defense treaty, and the commitments run through executive memoranda renewed roughly every decade, the latest for 2019 to 2028. What is structural is money and statute — the largest cumulative aid total of any country, a Qualitative Military Edge written into US law, a war reserve stockpile on Israeli soil, and the first free-trade agreement the United States ever signed. What the standard telling leaves out is that the United States has forced Israel to withdraw from territory under threat of sanctions, halted arms deliveries as a "reassessment," held up ten billion dollars in loan guarantees over settlements, and prosecuted an Israeli espionage operation run against it — and that in 1967 an Israeli attack on a US Navy ship killed thirty-four Americans. A record that omits those is not a record.
This page covers structure, not sentiment, and it argues neither for nor against the relationship. Its rule is symmetry: every category applied to the United Kingdom is applied here in the same words, and ruptures are listed whichever direction they ran. The 1963 thesis in the separate deep dive is a reading; it is linked as one and not repeated here.
