This is unsubstantiated antisemitism, and genocide-apologia. Arabs are justified in fighting the people who colonize them and expel them from their lands.

“There has been Anti-Semitism, the Nazis, Hitler, Auschwitz, but was that their fault? They see but one thing: we have come and we have stolen their country. Why would they accept that?” —David Ben-Gurion

"Agreement with Arabs Impossible at present... Zionism Must Go Forward" - Jabotinsky, 1923

“Let us not ignore the truth among ourselves … politically we are the aggressors and they defend themselves… The country is theirs, because they inhabit it, whereas we want to come here and settle down, and in their view we want to take away from them their country. … Behind the terrorism [by the Arabs] is a movement, which though primitive is not devoid of idealism and self sacrifice.” — David Ben Gurion. Quoted on pp 91-2 of Chomsky’s Fateful Triangle, which appears in Simha Flapan’s “Zionism and the Palestinians pp 141-2 citing a 1938 speech.

And just in case you justify the genocide on them being "foreign" Arabs, Ben Gurion had this to say as quoted by Shlomo Sand:

“The fellahin are not descendants of the Arab conquerors, who captured Eretz Israel and Syria in the seventh century CE. The Arab victors did not destroy the agricultural population they found in the country. They expelled only the alien Byzantine rulers, and did not touch the local population. Nor did the Arabs go in for settlement. Even in their former habitations the Arabs did not engage in farming…their whole interest in the new countries was political, religious and material: to rule, to propagate Islam, and to collect taxes…the Jewish farmer, like any other farmer, was not easily torn from his soil…Despite the repression and suffering the rural population remained unchanged.”
