Paul Oestreicher is right that "modern Israel was born in terror". But that terror was Arab terror that needed to be responded to. Arab terror in Jerusalem in April 1920; in Jaffa in May 1921; in Jerusalem in November 1921; in Hebron, Safed etc in 1929; throughout the mandate territory from April 1936 to May 1939. And Arab terror in response to the UN partition resolution beginning in December 1947. All this terror was initiated by the Arabs who refused any political resolution, any compromise or any mediation.
