Hanna Siniora, writer of ''A Generation That Does Not Fear Israeli Bullets'' {op-ed, Jan. 28}, is not as extreme as Yasser Arafat, but he distorts the reality and the causes of the current disturbances in Judea, Samaria and Gaza.

For example, Mr. Siniora describes the activities of the Palestinian Arabs in those territories as ''nonviolent resistance to the occupation, civil disobedience . . . or national disobedience.'' Nowhere in his article does he indicate that the Arabs use violence by throwing stones, burning tires, throwing fire bombs and stabbing with knives. Nowhere does he mention rioters' using lethal weapons.

Mr. Siniora's credibility is diminished by his denial of Arab violence used against Israeli soldiers and his failure to recognize that reasonable force to repel violence is justified to restore law and order.

Furthermore, blaming Israel alone for the plight of the Palestinian Arabs ignores the fact that Jordan occupied these same territories for 19 years (1948 to 1967) prior to the Israeli defeat of Jordan after Jordan's unprovoked attack on Israel. An independent Palestinian state was not demanded nor provided during those 19 years. Instead, the PLO was created to destroy Israel, and the PLO isstill a party to the present distur-bances.
