On October 10, 2019, at the memorial for the fatalities of the October 1973 War, Israeli Prime Minister and Defense Minister Binyamin Netanyahu spoke and focused on the rising Iranian threats on Israel.
He made bold at the possibility of both an Israeli preemptive military strike on Iran and the specter of a major protracted regional war.
He noted: “The current focus of aggression in the Middle East is the Iranian regime in Tehran. Iran is striving to tighten its grip on Lebanon, Syria, Iraq, Yemen, and the Gaza Strip. It is constantly arming its equipment with dangerous weapons and is attacking freedom of navigation in international shipping routes. It shot down a big US UAV [unmanned aerial vehicle], it launched a crude and unprecedented attack on Saudi Arabia’s oil fields, it repeatedly exceeds its own arrogance Iran threatens to wipe us off the map. It says explicitly: ‘Israel will disappear’. Time and time again, it tries to attack us, so we must stand ready to protect ourselves from the danger.”
Whenever Israel is challenged and its security is threatened, Netanyahu asserted, “we always remember and apply the basic rule that guides us: Israel will defend itself, on its own, in the face of every threat. The IDF [Israel Defense Force] is prepared to preempt any threat, defensively and offensively, with its overwhelming power in weaponry and in spirit.”
Two weeks before, on September 26, 2019, Netanyahu spoke during the New Year’s toast at the IDF General Staff forum. He warned the IDF High Command of gathering clouds and rising security challenges. “Israel’s proven capacity to simultaneously perform multiple missions is about to be challenged as never before,” he observed. “Hitherto we have navigated affairs boldly and responsibly in several arenas, at times simultaneously, but not so far in a comprehensive confrontation.”
This might change soon, Netanyahu warned, raising the specter of an all-out war as a distinct possibility. Such a war might erupt despite the great success of the myriad of strikes against Iran and Iran’s proxies throughout the region.
The difference in emphasis on Israel’s determination to act alone, audaciously and proactively, stems from two major developments. Official Jerusalem did not conceal its disappointment from the US about the US military abandonment of Kurdish fighters in northern Syria, coming on the heels of the US inaction in the Persian Gulf.
Israel now has to face the possibility of being left alone to confront a rising and assertive Iran.
A tweet by Israeli Special Forces reserve officer and former Security Cabinet member Naftali Bennett eloquently summed up the Israeli quandary: “Israel will ALWAYS defend itself by itself. The Jewish State will never put its fate in the hands of others, including our great friend, the USA.”
Unmentioned by Netanyahu and others in public were the most recent changes in Iranian doctrine and regional strategy which saw unprecedented emphasis being put on the destruction of Israel by both Iran and its myriad of proxies.
According to Middle East analyst Elijah Magnier, “Iran will never give up its advanced missile program, which enables the country to defend itself against any attacks and violations of its airspace — as, for example, happened with the US drone downed this  Summer. Moreover, for Iran to cease or continue supporting its allies in Palestine, Lebanon, Syria, Iraq, and Afghanistan is not a matter of choice. It is part of its ideology, its constitution, its very existence.”
