Israel said its strikes against Iran on Saturday were in retaliation for Tehran's strikes on Israel on Oct. 1, the latest exchange in an escalating conflict between the arch-rivals.

This was the latest in a wider escalation since the war in Gaza began last year, but Israeli-Iranian enmity stretches back decades through a history of clandestine wars and attacks by land, sea, air and cyberspace.

According to Reuters, following is a timeline of key events:

1979 - Iran's pro-Western leader, Mohammed Reza Shah, who regarded Israel as an ally, is swept from power in a Revolution that installs a new Shiite theocratic regime with opposition to Israel an ideological imperative.

1982 - As Israel invades Lebanon, Iran's Revolutionary Guards work with fellow Shiites there to set up Hezbollah. Israel will eventually see the group as the most dangerous adversary on its borders.
1983 - Iran-backed Hezbollah uses suicide bombings to expel Western and Israeli forces from Lebanon. In November a car packed with explosives drives into the Lebanon headquarters of Israel's military. Israel later withdraws from much of Lebanon.

1992-94 - Argentina and Israel accuse Iran and Hezbollah of orchestrating suicide bombings at Israel's embassy in Buenos Aires in 1992 and a Jewish center in the city in 1994, each of which killed dozens of people.
Iran and Hezbollah deny responsibility.

2002 - A disclosure that Iran has a secret program to enrich uranium stirs concern that it is trying to build a nuclear bomb in violation of its non-proliferation treaty commitments, which it denies. Israel urges tough action against Iran.

2006 - Israel fights Hezbollah in a month-long war in Lebanon but is unable to crush the heavily armed group, and the conflict ends in effective stalemate.

2009 - In a speech, Iranian Supreme Leader Ali Khamenei calls Israel "a dangerous and fatal cancer.”

2010 - Stuxnet, a malicious computer virus widely believed to have been developed by the US and Israel, is used to attack a uranium enrichment facility at Iran's Natanz nuclear site. It is the first publicly known cyberattack on industrial machinery.

2012 - Iranian nuclear scientist Mostafa Ahmadi-Roshan is killed by a bomb placed on his car by a motorcyclist in Tehran. A city official blames Israel for the attack.

2018 - Israeli Prime Minister Benjamin Netanyahu hails President Donald Trump's withdrawal of the US from Iran's nuclear deal with world powers after years of lobbying against the agreement, calling Trump's decision "a historic move.”

In May Israel says it hit Iranian military infrastructure in Syria - where Tehran has been backing President Bashar al-Assad in the civil war - after Iranian forces there fired rockets at the Israeli-occupied Golan Heights.

2020 - Israel welcomes the assassination of General Qassem Soleimani, commander of the overseas arm of Iran's Revolutionary Guards, in an American drone strike in Baghdad. Iran strikes back with missile attacks on Iraqi bases housing American troops. About 100 US military personnel are injured.

2021 - Iran blames Israel for the assassination of Mohsen Fakhrizadeh, viewed by Western intelligence services as the mastermind of a covert Iranian program to develop nuclear weapons capability. Tehran has long denied any such ambition.

2022 - US President Joe Biden and Israeli Prime Minister Yair Lapid sign a joint pledge to deny Iran nuclear arms in a show of unity by allies long divided over diplomacy with Tehran.

The undertaking, part of a "Jerusalem Declaration" crowning Biden's first visit to Israel as president, comes a day after he tells a local TV station he is open to a "last resort" use of force against Iran - an apparent move toward accommodating Israeli calls for a "credible military threat" by world powers.

April 2024 - A suspected Israeli airstrike on the Iranian embassy compound in Damascus kills seven Revolutionary Guards officers, including two senior commanders. Israel neither confirms nor denies responsibility.

Iran responds with a barrage of drones and missiles in an unprecedented direct attack on Israeli territory on April 13. This prompts Israel to launch a strike on Iranian soil on April 19, sources familiar with the matter say.

Oct. 1, 2024 - Iran fires over 180 missiles at Israel in what it calls revenge for the killing of Hezbollah leader Hassan Nasrallah on Sept. 27 in an airstrike on Beirut's southern suburbs, and the killing of Hamas chief Ismail Haniyeh in Iran's capital on July 31.

Oct. 26, 2024 - Israel strikes military sites in Iran, saying it was retaliating against Tehran's attacks earlier in the month. Iranian media reports explosions over several hours in Tehran and at nearby military bases. Iran reports "limited damage" to some locations.

It's Iran's move now.
How Iran chooses to respond to the unusually public Israeli aerial assault on its homeland could determine whether the region spirals further toward all-out war or holds steady at an already devastating and destabilizing level of violence.
In the coldly calculating realm of Middle East geopolitics, a strike of the magnitude that Israel delivered Saturday would typically be met with a forceful response. A likely option would be another round of the ballistic missile barrages that Iran has already launched twice this year, The Associated Press said.
Retaliating militarily would allow Iran's clerical leadership to show strength not only to its own citizens but also to Hamas in Gaza and Lebanon's Hezbollah, the militant groups battling Israel that are the vanguard of Tehran's so-called Axis of Resistance.
It is too soon to say whether Iran's leadership will follow that path.
Tehran may decide against forcefully retaliating directly for now, not least because doing so might reveal its weaknesses and invite a more potent Israeli response, analysts say.
“Iran will play down the impact of the strikes, which are in fact quite serious,” said Sanam Vakil, the director of the Middle East and North Africa program at the London-based think tank Chatham House.
She said Iran is “boxed in" by military and economic constraints, and the uncertainty caused by the US election and its impact on American policy in the region.
Even while the Mideast wars rage, Iran's reformist President Masoud Pezeshkian has been signaling his nation wants a new nuclear deal with the US to ease crushing international sanctions.
A carefully worded statement from Iran’s military Saturday night appeared to offer some wiggle room for Iran to back away from further escalation. It suggested that a cease-fire in the Gaza Strip and Lebanon was more important than any retaliation against Israel.
Supreme Leader Ali Khamenei, Iran's ultimate decision-maker, was also measured in his first comments on the strike Sunday. He said the attack “should not be exaggerated nor downplayed,” and he stopped short of calling for an immediate military response.
Saturday's strikes targeted Iranian air defense missile batteries and missile production facilities, according to the Israeli military.
With that, Israel has exposed vulnerabilities in Iran’s air defenses and can now more easily step up its attacks, analysts say.
Satellite photos analyzed by The Associated Press indicate Israel's raid damaged facilities at the Parchin military base southeast of Tehran that experts previously linked to Iran's onetime nuclear weapons program and another base tied to its ballistic missile program.
Current nuclear sites were not struck, however. Rafael Mariano Grossi, the head of the International Atomic Energy Agency, confirmed that on X, saying “Iran’s nuclear facilities have not been impacted.”
Israel has been aggressively bringing the fight to the Iranian-backed militant group Hezbollah, killing its leader and targeting operatives in an audacious exploding pager attack.
“Any Iranian attempt to retaliate will have to contend with the fact that Hezbollah, its most important ally against Israel, has been significantly degraded and its conventional weapons systems have twice been largely repelled,” said Ali Vaez, the Iran project director at the International Crisis Group, who expects Iran to hold its fire for now.
That's true even if Israel held back, as appears to be the case. Some prominent figures in Israel, such as opposition leader Yair Lapid, are already saying the attacks didn't go far enough.
Regional experts suggested that Israel's relatively limited target list was intentionally calibrated to make it easier for Iran to back away from escalation.
As Yoel Guzansky, who formerly worked for Israel’s National Security Council and is now a researcher at the Tel Aviv-based Institute for National Security Studies, put it: Israel's decision to focus on purely military targets allows Iran "to save face.”
Israel's target choices may also be a reflection at least in part of its capabilities. It is unlikely to be able to destroy Iran's nuclear facilities on its own and would require help from the United States, Guzansky said.
Besides, Israel still has leverage to go after higher-value targets should Iran retaliate — particularly now that nodes in its air defenses have been destroyed.
“You preserve for yourself all kinds of contingency plans,” Guzansky said.
Thomas Juneau, a University of Ottawa professor focused on Iran and the wider Middle East, wrote on X that the fact Iranian media initially downplayed the strikes suggests Tehran may want to avoid further escalation. Yet it's caught in a tough spot.
“If it retaliates, it risks an escalation in which its weakness means it loses more,” he wrote. “If it does not retaliate, it projects a signal of weakness.”
Vakil agreed that Iran's response was likely to be muted and that the strikes were designed to minimize the potential for escalation.
“Israel has yet again shown its military precision and capabilities are far superior to that of Iran,” she said.
One thing is certain: The Mideast is in uncharted territory.
For decades, leaders and strategists in the region have speculated about whether and how Israel might one day openly strike Iran, just as they wondered what direct attacks by Iran, rather than by its proxy militant groups, would look like.
Today, it's a reality. Yet the playbook on either side isn't clear, and may still be being written.
“There appears to be a major mismatch both in terms of the sword each side wields and the shield it can deploy,” Vaez said.
“While both sides have calibrated and calculated how quickly they climb the escalation ladder, they are in an entirely new territory now, where the new red lines are nebulous and the old ones have turned pink,” he said.
