IDF

Hebrew: צַהַ״ל

The Israel Defense Forces (Tzahal), the military of the State of Israel, founded 1948.

Etymology and name

“IDF” translates Hebrew Tzva HaHagana LeYisrael (צבא ההגנה לישראל), literally “Army for the Defense of Israel.” Its acronym, צה”ל (Tzahal), is the name Israelis actually use day to day; “IDF” is the standard English rendering used in foreign reporting and by the military’s own English-language spokesperson’s office. The word choice is deliberate and old: “Haganah” (הגנה, “defense”) was already the name of the pre-state Jewish self-defense organization the IDF absorbed, so the new army’s name carried the same defensive framing forward rather than adopting an offensive or expansionist title.

Founding and structure

The IDF was established by Defence Army of Israel Ordinance No. 4, issued by the Provisional Government and signed by Prime Minister David Ben-Gurion on 26 May 1948, twelve days after Israel’s Declaration of Independence. The ordinance unified the Haganah, the largest and officially recognized pre-state defense force, together with the Palmach, its elite strike companies, and the militias of the Irgun and Lehi, whose separate units and command structures were dissolved and folded into the single national army over the following months. It is a conscript force: most Jewish and Druze citizens serve from age 18, men roughly three years and women roughly two, with an active reserve system that can mobilize hundreds of thousands within days, a structure built directly out of the emergency mobilization the 1948 war demanded.

The record

The IDF has fought in every major Arab-Israeli war: 1948, the 1956 Suez campaign, the 1967 Six-Day War, the 1973 Yom Kippur War, the Lebanon wars of 1982 and 2006, the Gaza operations of 2008, 2012, 2014, and 2021, and the war launched by Hamas’s 7 October 2023 invasion. Israeli military doctrine formally includes “purity of arms” (tohar haneshek), a code obligating restraint and proportionate force, and the IDF is one of few militaries with a standing legal branch (the Military Advocate General) that opens criminal investigations into its own soldiers, a process examined in does Israel hold its own soldiers accountable for killing Arabs. It also employs documented duty-to-warn practices, leaflets, phone calls, and roof-knock strikes ahead of targeting buildings, a practice with no equivalent among the region’s other combatants. The record is not spotless: the 1982 Sabra and Shatila massacre, carried out by allied Lebanese militia while the IDF held the perimeter, produced Israel’s own Kahan Commission finding indirect responsibility and forcing Defense Minister Ariel Sharon’s resignation, and the 2002 Jenin operation produced disputed but real civilian deaths that Human Rights Watch investigated and found fell well short of the “massacre” claimed at the time. The IDF’s own February 2025 internal inquiry acknowledged serious failures that allowed the October 7 attack to succeed.

Misuse and accurate usage

Anti-Israel activism frequently substitutes “IOF,” Israel Occupation Forces, a term with no official standing that recasts a sovereign state’s military as an inherently illegitimate occupying force before any argument is made, the same rhetorical move examined at occupied vs. disputed. Coverage of Gaza casualties routinely omits that the IDF’s own combatant counts, drawn from named-fighter identification, run far higher than headline totals suggest, detailed at how many people have died in Gaza and how many were combatants. Claims that the IDF fights carelessly ignore the extensive record of Hamas using civilian sites as cover, covered at human shields in the Israeli-Palestinian conflict. The accurate usage is simple: the IDF is Israel’s national military, structurally accountable to civilian government and to its own courts, operating in wars it has documented but not always started.
