There really ONLY one way to resolve this, IMHO.
That is a Two-State Solution. The Zionists have made clear during the 1940s, they didn't want a One State Solution.
Clear from these statements back then:
“If it was permissible to move an Arab from the Galilee to Judea, why it is impossible to move an Arab from Hebron to Transjordan, which is much closer? There are vast expanses of land there and we are over crowded….Even the High Commission agrees to a transfer to Transjordan if we equip the peasants with land and money. If the Peel Commission and the London Government accept, we’ll remove the land problem from the agenda.”
The Arabs, Ben-Gurion claimed, would not become landless as a result of Zionist land acquisition; they would be transferred to Transjordan.
October 29, 1936 the 21 member of the Jewish Agency Executive endorsed the proposal of a transfer of displaced Arab farmers to Transjordan. Only two of the four non-Zionist members opted to dissent.

12 July 1937, Ben-Gurion entered in his diary: “The compulsory transfer of the Arabs from the valleys of the proposed Jewish state could give us something which we never had, even when we stood on our own feet during the days of the First and Second Temple”
– a Galilee free from Arab population.
Ben-Gurion went so far to write: “We must prepare ourselves to carry out” the transfer.
27 July 1937, Ben-Gurion wrote in a letter to his 16 year old son Amos: “We have never wanted to dispossess the Arabs [but] because Britain is giving them part of the country which had been promised to us, it is fair that the Arabs in our state be transferred to the Arab portion”
5 October 1937, Ben-Gurion wrote in a letter to his 16 year old son Amos: “We must expel the Arabs and take their places…. And, if we have to use force-not to dispossess the Arabs of the Negev and Transjordan, but to guarantee our own right to settle in those places- then we have force at our disposal.”
So the Only Reasonable way forward is a Two-State Solution. Or we will continue to see these killings repeated again and again.
Countries need to resist the pressure from "Interested" groups and do what is right for humanity.
