Then enlighten me. Which of the major wars in the region did Israel start?
1948 first Arab Israeli war?
1956 Suez crisis?
1967 Six day war? (You can argue here that Israel did a preemptive strike but it's a fact that the Arab alliance would have attacked Israel if they didn't.)
1973 Jom Kippur war?
As
@B20 posted earlier, Suez 1956, the Six-Day War, and Lebanon 1982 are clear cut cases of Israel initiating the conflict. Of course in each case Israel had a
casus belli, and 1967 may have been the most legitimate although it’s not an established “fact” that Egypt was going to go to war, we can’t know for certain. In any case almost every act of war is preceded by some sort of justification, and this is no less true for those wars initiated by the Arab powers.
In addition to the above, Israel has bombed Lebanon, Syria, Jordan, Iraq, Egypt, Sudan, and Tunisia outside of direct hostilities, and engaged in numerous other clandestine operations around the world whose legality is, let’s say, doubtful. Again you can argue whether or not each case is justified on its own merits, but the broader pattern is one of Israel taking the initiative.
(edit): I would add that, in the context of this thread, it is certainly Iran that went looking for a conflict with Israel after 1979. But even then the growth and apparent intractability of the confrontation between the two cannot be understood without reference to the Israeli occupation of southern Lebanon.
