Self-defense is the primary
just cause for war.
Since Israel initially acted in self-defense—invading the West Bank only after receiving fire from Jordanian troops—the initial 1967 occupation of the West Bank passes the test of
just cause.
The case for
just cause in the post-1967 occupation is much weaker. In the immediate aftermath of the war,
U.N. Resolution 242 emphasized the “inadmissibility of the acquisition of territory by war” and called for “withdrawal of Israeli armed forces from
territories occupied in the recent conflict.” Instead of complying, Israel unilaterally annexed East Jerusalem and maintained its armed forces throughout the entire West Bank. This action was not a matter of self-defense, since Jordan had cooperated with the U.N. ceasefire and was no longer an immediate threat. Now, fifty years later and especially after the 1994 peace treaty between Israel and Jordan, the country is no longer a threat to Israel. Thus, Israel’s refusal to end the occupation of the West Bank has no
just cause inherent to the conditions that led it to initially occupy the territory.
