MOSHE PHILLIPS, AFSI -- The story of Eli Cohen's life should be recalled today even if he had never gone undercover in Syria. 

When Eli Cohen was publicly executed by the government of Syria on May 18, 1965, it was clear to Israelis and Syrians that he had succeeded in becoming a friend of the president of Syria, and had penetrated the innermost Syrian government circles. What was not yet known, however, was that he had gathered the intelligence that would later save the State of Israel from being destroyed.

More than any other one man, Eli Cohen, an Egyptian-born Jew, earned the Mossad its reputation as one of the best intelligence services in the world, and paved the way for Israel to win on the Golan front in the Six-Day War in June 1967.

He was deeply moved as a young man in Cairo by the 1944 trial of two members of the Stern Group (the LEHI), Eliahu Bet-Zouri and Eliahu Hakim. Hakim and Bet-Zouri were the assassins of the anti-Semitic British High Commissioner of the Middle East, Lord Moyne.

The young Cohen helped to organize demonstrations in support of Bet-Zouri and Hakim. The demonstrations proved fruitless. The men were sentenced to hang, but on the scaffold they maintained their dignity and self respect, and sang Israel's national anthem, "Hatikvah." It has been said that thoughts of Bet-Zouri and Hakim bolstered Cohen as he himself was led to be executed.

Later, Cohen was instrumental in establishing an "Underground Railroad" that smuggled Egyptian Jews to Israel. In the early 1950s, Cohen was recruited by the Mossad to participate in an espionage operation that spied on Nasser's ex-Nazi scientists, who were attempting to build rockets; reportedly, Cohen also engaged in sabotage.

After the Mossad activities in Egypt were discovered and most members were rounded up, Cohen moved to Israel in 1956. After a brief time adjusting to life in Israel and his service in the Israel Defense Forces, Cohen was approached to become an information analyst for the Mossad.

The Mossad eventually accepted Cohen's request for field duty.

Cohen adopted the persona of a rich Arab merchant who had emigrated to Argentina and then returned to his Syrian homeland, calling himself Kamal Amin Taabes. Under this cover, Cohen gained access to the most influential sectors of Damascus society, and joined the revolutionary Arab Socialist Ba'ath Party.

Cohen became very active in the party, and friendly with its leaders. After a coup d'etat, the Ba'ath Party came to power -- and remains in power until today. Among the men Cohen had befriended, many became officials in the new government and were high-ranking military officers -- including the head of intelligence, Colonel Ahmad Suweidani, and Syrian President Amin al-Hafiz.

Cohen was among the only civilians to ever inspect Syrian installations on the Golan Heights. He was able to send photographs and sketches of the entire Syrian front-lines back to the Mossad. In one case, he was able to warn Israel of an impending attempt by Syrian commandos to cross the border.

In addition to his espionage work, Cohen was assigned to assassinate escaped Nazi war criminal Franz Rademacher, who was living in a Syrian colony of ex-Nazis. The 1962 attempt on Rademacher failed. Alois Brunner, Adolf Eichmann's right-hand man, was another Nazi who was offered refuge by Syria. Cohen participated in an attempt to target Brunner as well. This part of Syrian history is well worth reflecting on today: even before Assad came to power the Syrian government hated Jews so much that it offered a haven to Nazi war criminals. Famed Nazi hunter Simon Wiesenthal labeled Brunner as "doubtless the worst...living criminal of the Third Reich" in 1988.

When Cohen was finally discovered, quite by accident when his radio equipment was detected by KGB agents, he was being seriously considered to become either Minister of Defense or Assistant Foreign Minister.

After two lengthy trials, Eli Cohen was finally sentenced to death by hanging. Cohen was 40 years old, and left a widow, three daughters, and a son. In his final letter to his wife, he wrote "I beg of you not to waste time crying for me. Always think of the future."

Cohen left advice for future leaders of Israel. He once said, "Against the Arab you mustn't defend yourself. You must attack..."

Eli Cohen's advice was adhered to by the late Menachem Begin in 1981, when he was prime minister and ordered the Israeli Air Force to destroy the Iraqi nuclear plant at Osirak. The strike on Osirak established the Begin Doctrine, which unconditionally declared that the surprise raid was not a one time thing, but, as Begin himself explained a June 15 interview on CBS's Face the Nation "This attack will be a precedent for every future government in Israel. ... Every future Israeli prime minister will act, in similar circumstances, in the same way."

The doctrine could have just as easily been called the Eli Cohen Doctrine.

Let us hope that the doctrine is not ever forgotten.
