One might expect that only historians would care to revisit the 1948 war that created Israel. And yet the debate about what constitutes truth and myth from that period still provokes raw emotions.
Much rests on how those events are reconstructed, not least because the shock waves have yet to subside. Israelis fear, and Palestinians crave, a clearer picture of the past because it would powerfully illuminate the present. It might also influence the international community's proposed solutions for the conflict.
It comes as Moshe Yaalon, the defence minister, this week accused Breaking the Silence, an Israeli organization that exposes military abuses, of "treason" for collecting evidence from the army's current whistleblowers.
Western understandings of the 1948 war -- what Palestinians term their Nakba, or catastrophe -- are dominated by an enduring Israeli narrative. Israel's army, it is said, abided by a strict moral code. Palestinians left not because of Israel's actions but on the orders of Arab leaders.
In this rendering, the Palestinians' mass dispossession was the fault of the Arab world -- and a solution for the millions of today's refugees lies with their host countries.
For decades Israel's chief concession to the truth was an admission that a massacre took place just outside Jerusalem, at Deir Yassin.
Israel claimed the atrocity was the exception that proved the rule: a rogue militia killed more than 100 villagers, violating Israel's ethical codes in the chaotic weeks before statehood was declared.
Palestinians have always known of dozens of other large massacres of civilians from 1948 carried out by the Israeli army. The barbarity, they say, was intended to terrorize the native population into flight. This account puts responsibility on Israel for taking the refugees back.
But history is written by the victor.
In recent decades a few brave Israeli scholars have chipped away at the official facade. In the late 1990s a Haifa University student collected testimonies from former soldiers confirming that over 200 Palestinians had been massacred at Tantura, south of Haifa. After the findings were made public, he was pilloried and stripped of his degree.
A decade ago, the historian Ilan Pappe wrote a groundbreaking book, The Ethnic Cleansing of Palestine, arguing that massacres like the one at Tantura were exploited to drive out Palestinians. He and others noted the suggestive titles of military operations such as "Broom" and soldiers' orders to "clean" areas.
Pappe now lives in academic exile in the UK.
The biggest obstacle to shifting Israeli and western perceptions of 1948 has been the lack of a clear paper trail connecting the political leadership to the massacres. Israel locked away bundles of documentation precisely not to jeopardise the official narrative.
But things are changing slowly.
Last year a key deception was punctured: that Israel urged many of the war's 750,000 Palestinian refugees to return. In a letter to Haifa's leaders shortly after the city's Palestinians were expelled, David Ben Gurion, Israel's first prime minister, demanded that any return be barred.
Now another letter, located by Israeli historian Yair Auron and published last week for the first time in English by the Haaretz newspaper, trashes the idea of an ethical Israel army.
