Protecting Israel's air traffic is high priority for the Shin Bet security service, right up there with protecting Israeli embassies abroad. Thus, had Hezbollah actually attacked a plane successfully, this would have been tantamount to declaring war.Agents of Iran and its Lebanese proxy, Hezbollah, have had a difficult time lately killing Israelis. Law enforcement agencies across the globe have stopped Iranian plots in Kenya, Georgia, India, Azerbaijan and Thailand. But remember that Iran every so often succeeds, as it did, twice, in Argentina, blowing up both a Jewish community center and the Israeli embassy. So it's entirely possible that Iranian agents could succeed again, and then we'd be looking at an accelerated conflict. As Harel points out:
Israeli leaders have significantly lowered the volume of their own threats against Iran recently. But at a time when Israel's dilemma on Iran has been boiled down to a four-word slogan, "bomb or be bombed," a third scenario must also be considered: A poorly-thought-out Iranian move, in the Persian Gulf or elsewhere, could ignite a conflict even before anyone decides to attack its nuclear facilities.
