WASHINGTON -- Next June will mark the 40th anniversary of the Six Day War. For four decades we have been told that the cause of the anger, violence and terror against Israel is its occupation of the territories seized in that war. End the occupation and the ``cycle of violence'' ceases.

The problem with this claim was that before Israel came into possession of the West Bank and Gaza in the Six Day War, every Arab state had rejected Israel's right to exist and declared Israel's pre-1967 borders -- now deemed sacred -- to be nothing more than the armistice lines suspending, and not ending, the 1948-49 war to exterminate Israel.

But you don't have to be a historian to understand the intention of Israel's enemies. You only have to read today's newspapers.

Exhibit A: Gaza. Just last September, Israel evacuated Gaza completely. It declared the border between Israel and Gaza an international frontier, renouncing any claim to the territory. Gaza became the first independent Palestinian territory in history. Yet the Gazans continued the war. They turned Gaza into a base for launching rocket attacks against Israel and for digging tunnels under the border to conduct attacks like the one that killed two Israeli soldiers on June 25 and yielded a wounded hostage brought back to Gaza. Israeli tanks have now had to return to Gaza to try to rescue the hostage and suppress the rocket fire.

Exhibit B: South Lebanon. Two weeks later, on July 12, the Lebanese terror organization, Hezbollah, which has representation in the Lebanese parliament and in the Cabinet, launched an attack into Israel that killed eight soldiers and wounded two, who were brought back to Lebanon as hostages.

What's the grievance here? Israel withdrew from Lebanon completely in 2000. It was so scrupulous in making sure that not one square inch of Lebanon was left inadvertently occupied that it asked the U.N. to verify the exact frontier defining Lebanon's southern border and retreated behind it. This ``blue line'' was approved by the Security Council, which declared that Israel had fully complied with resolutions demanding its withdrawal from Lebanon.

Grievance satisfied. Yet what happens? Hezbollah has done to South Lebanon exactly what Hamas has done to Gaza: turn it into a military base and terrorist operations center from which to continue the war against Israel. South Lebanon bristles with Hezbollah's ten-thousand Katyusha rockets that put northern Israel under the gun. Fired in the first hours of fighting, just 85 of these killed two Israelis and wounded over 100 in Israel's northern towns.

Over the last six years, Hezbollah has launched periodic raids and rocket attacks into Israel. Israeli retaliation has led to the cessation of these provocations -- until the next time convenient for Hezbollah. Wednesday was such a time. One terror base located in fully unoccupied Arab territory (South Lebanon) attacks Israel in support of another terror base in another fully unoccupied Arab territory (Gaza).

Why? Because occupation was a mere excuse to persuade gullible and historically ignorant Westerners to support the Arab cause against Israel. The issue is, and has always been, Israel's existence. That is what is at stake. Continued...
