Acknowledging the fact that multiple crimes against humanity took place against the Palestinians before Ben Gurion unilaterally declared Israel a state on the 14th May 1948, doesn't quite fit the narrative of the "angry Arabs were out to annihilate us".
Plan Dalet the Israeli plan to ethnically cleanse Palestine had been in operation for months, quotes from Ben Gurion:
"We must expel Arabs and take their places...and, if we have to use force... then we have force at our disposal." (from Nur Masalha, Expulsion of the Palestinians, p. 66)
"The compulsory transfer of the [Palestinians] from the valleys of the proposed Jewish state could give us something which we never had, even when we stood on our own during the days of the first and second Temples. We are given an opportunity which we never dared to dream of in our wildest imaginings." (from Benny Morris, Righteous Victims, p. 142)
"In many parts of the country new settlement will not be possible without transferring the [Palestinian peasants]... Jewish power, which grows steadily, will also increase our possibilities to carry out the transfer on a large scale." (from Righteous Victims, p. 143)
"With compulsory transfer we [would] have a vast area [for settlement]. I support compulsory transfer. I don't see anything immoral in it." (from Righteous Victims, p. 144)
That "compulsory transfer" included many massacres in Palestinian villages,
here is a letter written a UK delegation to the UN regarding the attack on Deir Yassin which happened on 9th April 1948:
(1) The operation is believed to have been a joint National Military Organisation – Stern Group enterprise undertaken with the knowledge of the Haganah.
(2) The deaths of some 250 Arabs, men, women and children, which occurred during this attack, took place in circumstances of great savagery.
(3) Woman and children were stripped, lined up, photographed, and then slaughtered by automatic firing and survivors have told of even more incredible bestialities.
(4) Those who were taken prisoner were treated with degrading brutality.
(5) Although the Haganah is unable to deny that it gave covering fire to the terrorists responsible for this outrage, the action as a whole has been condemned by the Jewish press and denounced by the Chief Rabbinate.
(6) Owing to other pre-occupations, the Security Forces were not in a position to act before the 14th April, for which day an air strike at Deir Yassin was arranged.
(7) On the 13th April, it became apparent that the Haganah had taken over the village from the terrorists, and the operation was, therefore, suspended.
(8) The Government of Palestine reported on the 14th April that it had not yet been possible to enter Deir Yassin and that a Jewish Police Officer sent to investigate was not allowed by the Haganah to proceed beyond Givat Shaul.
(9) A representative of the International Red Cross who visited Deir Yassin on the 11th April is said to have stated that in one cave he saw heaped bodies of some 150 Arab men, women and children, whilst in a stronghold a further 50 bodies were found.

Thankfully there are lots of historical records that document what happened.
