Fall of Assad, rise of Trump: Why 2024 was a very bad year for Iran

The fall of Syria’s Bashar al-Assad was the crescendo of a remarkably bad year for the Iranian regime. 

The Islamic Republic suffered major blows in Gaza, Lebanon and Syria, diminishing the power of its so-called Axis of Resistance. Its currency officially became the lowest valued in the world and when Israel decimated its proxy forces, the U.S. elected a president whom Iran so despises that it spent years trying to assassinate him. 

Here’s a look back at blows suffered by Ayatollah Ali Khameini and his regime over the past year: 

In April, Israel bombed the Iranian embassy in Syria, prompting Iran to strike back with more than 300 drones and missiles aimed into Israel. But Israel worked with the U.S., Jordan and Saudi Arabia to shoot down nearly every missile and drone. 

The late Iranian president Ebrahim Raisi was killed in a helicopter crash while visiting a remote area. Iran has blamed the crash on dense fog. Raisi was a protégé and potential successor of Iran’s supreme leader, Khameini. 

While Iran inaugurated a new president this summer, Israel infiltrated to take out Hamas commander Ismail Haniyeh while he was visiting Tehran for the inauguration. While Haniyeh was staying in a VIP government guest house, Israel detonated a remote-controlled bomb. 

TRUMP TANGLES WITH REPORTER ON IRAN PRE-EMPTIVE STRIKE: 'IS THAT A SERIOUS QUESTION?'

Israel Defense Forces (IDF) took out Hamas head Yahya Sinwar after encountering him on a routine patrol in the Gaza city of Rafah. Sinwar was the mastermind behind the Oct. 7, 2023, attacks on Israel and was one of the most wanted men of the war. 

Hamas has lost thousands of fighters and much of its leadership ranks to Israel’s attacks and is nowhere near the threatening force on Israel’s borders Iran hoped it would be. 

Iran’s currency tanked to an all-time low upon news of the Trump election, and the expectation that he might bring back a "maximum pressure" policy. 

The Iranian rial is down 46% this year, making it officially the least-valuable currency in the world.

Iran has long vowed revenge for Trump approving the 2019 killing of Gen. Qassem Soleimani – and U.S. intelligence revealed Tehran plots to kill the president-elect. 

After the Trump administration pulled out of the Iran nuclear deal in 2018, it imposed harsh sanctions on the regime to stop its funding of proxies abroad, banning U.S. citizens from trading with Iran or handling Iranian money. 

It also punished entities in other countries that did business with Iran, by cutting them off from the dollar. 

TENSIONS BETWEEN ISRAEL AND TURKEY ESCALATE OVER SYRIA: 'IT’S TIME TO PAY ATTENTION'

President Joe Biden often waived enforcement of such sanctions, keen to bring Tehran back to the negotiating table to prevent it from acquiring nuclear weapons and fearful of driving up global oil prices. 

Iran gained access to more than $10 billion through a State Department sanctions waiver that allowed Iraq to continue buying energy from Iran, which the Biden administration argues is necessary to keep lights on in Baghdad.  

In the fall, Israel reoriented much of its efforts toward pummeling Hezbollah after a series of cross-border attacks from the Lebanese militant group. Israel targeted Hezbollah’s leadership and detonated hundreds of pagers the group had been using to communicate. At the end of November, Hezbollah agreed to a ceasefire where it and Israel must both end their armed presences in southern Lebanon. 

Both sides have claimed the other has broken the fragile truce, but it has ostensibly held for weeks.  

Syrian rebels sent Iran's Quds forces, an extension of the Revolutionary Guard Corps, running as they captured Damascus and pushed out President Bashar al-Assad. Iran's forces had been in Syria propping up Assad since civil war broke out in 2011, but had been diminished since the outbreak of war elsewhere in the Middle East. 

Syria's new government is set to be run by Sunni Muslims, hostile to Iran's Shiite government. And Iran lost a key supply line through Syria it had used to arm Hezbollah in its fight against Israel.
