From the River to the Sea. Who started that?

Irgun emblem. The map shows both Mandatory Palestine and the Emirate of Transjordan, which the Irgun claimed in its entirety for a future Jewish state. The acronym "Etzel" is written above the map, and "raq kach" ("only thus") is written below.

The Irgun policy was based on what was then called Revisionist Zionism founded by Ze'ev Jabotinsky

Two of the operations for which the Irgun is best known are the bombing of the King David Hotel in Jerusalem on 22 July 1946 and the Deir Yassin massacre that killed at least 107 Palestinian Arab villagers, including women and children, carried out together with Lehi on 9 April 1948.

The organization committed acts of terrorism against Palestinian Arabs, as well as against the British authorities, who were regarded as illegal occupiers. In particular the Irgun was described as a terrorist organization by the United Nations, British, and United States governments; in media such as The New York Times newspaper; as well as by the Anglo-American Committee of Inquiry, the 1946 Zionist Congress and the Jewish Agency. Albert Einstein, in a letter to The New York Times in 1948, compared Irgun and its successor Herut party to "Nazi and Fascist parties" and described it as a "terrorist, right wing, chauvinist organization".

Following the establishment of the State of Israel during the 1948 Palestine war, the Irgun began to be absorbed into the newly created Israel Defense Forces. Conflict between the Irgun and the IDF escalated into the Altalena affair, and the Irgun did not formally disband until January 12, 1949. The Irgun was a political predecessor to Israel's right-wing Herut (or "Freedom") party, which led to today's Likud party. Likud has led or been part of most Israeli governments since 1977.

The original 1977 party platform stated that "between the Sea and the Jordan there will only be Israeli sovereignty."
