He then joined the Zionist Commission as a press officer and helped expand the Jewish Telegraphic Agency upon his return to the United States, of which he served as editor.

His report was idealised, focusing on success and cultural connections, while avoiding mentions of many interpersonal conflicts and other disappointments among recruits; months after it was published, Agron expressed distaste at his own words, including his kindness to write that the English soldiers' fortune to not be stationed in the Tell El Kebir desert with the Americans was accidental.

[9]: 206  Agron was demobilised locally in 1920; he spent his last months in the military working in the Orderly Room and, upon discovering Legion records would likely be destroyed afterwards, "borrowed these papers for safe keeping".

[8] From 1920 to 1921, he worked for the Press Office of the Zionist Commission as a public relations attaché there;[18][9]: 201  in 1921 he was the head of the Zionist Commission Press Office,[1] a position that took him to the United States on the SS Rotterdam in April that year as a member of Chaim Weizmann's WZO delegation with Albert Einstein, Menachem Ussishkin, Shlomo Ginossar, and Ben Zion Mossensohn.

As it is, two or three non-Zionist items make even a downright Zionist item acceptable [...] My stuff, though it may not deal with Zionism or even anything Jewish breathes a spirit of constructive optimism, predisposing the reader to see that in Palestine there is a state of 'normalcy,' where Zionist reconstruction can be taken for granted.As the director of the press for Zionism and Jewish Palestine, his main duties were to advocate on behalf of the Yishuv to the world, encouraging tourism and immigration through relationships with the global media.

[36] Gershon Agronsky ... launched the paper with the idea that it would present the case of yishuv, or Jewish establishment in Palestine, to the representatives of the British Mandatory regime in a language and style that they could understand.

Lurie was immediately invested and borrowed money from his father to take Agron to London so that they could raise funds to start The Palestine Post; succeeding, they ran the first copy on 1 December 1932.

[7]: 39  Initially, it had a circulation of 1,200, was distributed around Palestine, and was predominantly read by the British soldiers and German immigrants; Agron tailored the content to the readers, for example, including cricket results and cartoons.

[7]: 41 [19] The Post was heavily aligned with the Israeli Labor Party (at the outset, Mapai) from the beginning, and Agron as well as successive editors made no secret that the newspaper was more interested in advocating for the state than freedom of the press.

[10] Kinneret College historian Giora Goodman wrote that, in terms of Jewish Agency media propaganda, the Palestine Post was "of greatest value", saying that, while nominally independent, the Post was recognised as "its semi-official mouthpiece"; Goodman noted that Agron was held in high regard, advising the Jewish Agency press bureau and espousing that "the best propaganda is produced by non-official means".

[39][40] When the 1936–1939 Arab revolt in Palestine broke out, more British troops arrived, and circulation went up to around 20,000;[7]: 41  it became more widespread and successful during World War II, when Allied soldiers spent much time in the Middle East.

Agron became a war correspondent, covering the North African campaign from 1941 to 1943; he also visited Turkey in 1942 and was there when the MV Struma, carrying Jewish refugees from Europe, sank, which he blamed on the Allies.

The Post, in part because of British mandatory policy in Palestine, made efforts to serve as an anti-Nazi "fighting paper", but the sides did not always agree: continuing to report on Arab terrorism saw an issue censored in 1936, and writing scathing articles against the White Paper of 1939 (the British imposing more restrictions on Jews living in Palestine) and deportations to Mauritius left the published newspaper full of white blank spaces.

[15] In June 1945, following World War II, Hans Morgenthau requested Agron write to US president Harry S. Truman to update him on the mood of the Jews in Palestine, particularly in response to the White Paper of 1939.

[12] The next day's edition was still printed, though short; the bombing, and the rumour that British officers may have helped the Arabs execute it, saw the Yishuv turn Jerusalem into a front line, closing the streets and manning them.

[15][18] No longer needing to remain pro-British, the purpose of the newspaper also changed, and the board took advantage of the fact that it would be the only local Palestinian news that most foreign diplomats could read, turning it into a "key vehicle" defending Israel.

[8] He had been asked to take the position during the war, in a telegram from Moshe Sharett; though Agron took it out of duty, he had been hoping to be named Israel's ambassador to Britain.

As mayor, he inherited many problems, particularly facing financial challenges after years of great spending trying to recover from the Battle for Jerusalem during the Palestine War.

Under Agron, there were many fewer fights in the city council, and those which did happen he could reportedly end quickly by reminding the chamber that time also cost money.

[15] Historian Howard Morley Sachar lauded the achievements of cultural and construction projects planned and approved by Agron, but he also had detractors due to his modernisation of the city, with protesters creating caricatures of him in the uniform of a Nazi officer.

[9]: 202–203 [10] In 1926, he defended the large sum paid to Hayim Nahman Bialik to undertake a tour of the United States so that his poetry could elevate Zionist propaganda there.

[48] In a fortieth-anniversary publication, The Jerusalem Post noted that Agron's initial policy directive for the newspaper was written as a business mission statement but "was, in fact, the climactic expression of years of thought on the Zionist question".

[7]: 39  However, on a 1952 visit to the United States, Agron is reported to have said: "We [people of Israel] are no longer concerned with the attitude of others… Once, Jewish public relations were a delicate matter… Now, only our actions are significant.

"[49] Agron wrote in 1925 that, to build a successful society in Palestine, the Yishuv required many American Jews, though he was careful to warn that these potential immigrants must understand what migration would mean.

She noted that she struggled to empathise with Holocaust survivors who arrived, saying this was due to an "unjustified arrogance" stemming from Zionist education which saw non-Palestinian Jews as other.

[56] The Agronsky children attended Beit Hakerem High School, where Varda was a classmate of Avshalom Haviv and Shmuel Kaufman, son of Judah Even Shemuel.

She attended William Penn High School and Goucher College,[59] where she was elected as a member of the Phi Beta Kappa honor society in 1917.

[62][63] This council typically saw socialite wives on its board, including Ethel Agronsky; she took her role seriously, campaigning for children and writing for Hadassah Magazine.

[62][64] During the Israel-Palestine war, Ethel helped to run the emergency Hadassah medical centres, in secret locations and often without water, power, or supplies, to treat the casualties.

[65][66][67][68] As a leading figure in the Haganah, Dani Agron controlled the secret flying school and its pilots, as well as other aerospace concerns, including around Rome as it served as a transition ground for volunteers to fight for Israel against Palestine.
