IDF Relearning the Basics While Modernizing for Future Threats

JNS.org – The Israel Defense Forces and the Defense Ministry must soon make significant decisions about the future structure and capabilities of the military, prompted by lessons learned from the war it has fought since Oct. 7, 2023, and the changing threat landscape.
In the coming months, the IDF will have to propose a multi-year force-building plan, which needs to receive government budgetary commitment to be implemented, to replace the previous plan, Momentum, which began in 2020 and continued until the war broke out.
Momentum helped establish a network-centered war machine, in which IDF branches cooperated to quickly detect and fire on enemy targets. Momentum argued that seizing enemy territory isn’t the most important thing, placing the emphasis instead on destroying enemy capabilities.
Eado Hecht, a senior research fellow at the Begin-Sadat Center for Strategic Studies and an analyst specializing in military theory and military history, told JNS there are several lessons for the IDF to learn from the war.
“Starting about 30 years ago, the IDF adopted an incorrect theory of future wars based on an incorrect appraisal of the direction of international politics in general and in the Middle East in particular,” Hecht said.
This mistaken assessment was a local version of “the end of history fallacy,” he added, the expectation that major wars and conflicts were a relic of history. Instead, the expectation was that modern technology and revolutions in warfare would enable Israel to make do “with only counter-guerilla, counter-terrorism capabilities,” and that hi-tech intelligence and air force capabilities would be sufficient to defeat any threat.
This theory led the IDF to downgrade its ground forces, Hecht noted, leading to a huge reduction in size, in which units were canceled and tens of thousands of personnel discharged from service, alongside the removal of a wide variety of weapon types from use. “Fields of knowledge necessary to conducting massed ground maneuvers were erased from training regimens,” he said.
“The first lesson of this war is that what became derogatorily known as ‘the old-type wars’ were not old or gone—they still exist and still require the same type of forces they did then and the same type of military theories, doctrine and training they did then. The IDF needs to relearn and rebuild its capability and competence in conducting massed ground forces maneuvers,” said Hecht.
“The second major lesson of the war is that the IDF had reduced its size to a point where it was barely capable of doing what was needed, in fact less than what was needed,” he said.
Two-front wars
While in the 1967 Six-Day War and the 1973 Yom Kippur War, the IDF was able to carry out defensive and offensive operations on two fronts simultaneously, against armies stronger than Hamas and Hezbollah, in the current Swords of Iron war, the IDF could defend on two fronts but only conduct offensive actions on one front at a time, Hecht said. Even on one front, the IDF had to act sequentially rather than simultaneously attack enemy forces across the board.
“The IDF will have to again increase the size of its ground forces. The answers to the questions ‘How much does it need?’ given the size and character of the future threats, and ‘How much can it expand?’ given the size of Israel’s manpower pool and economy, create a difficult tension that will have to be resolved gradually over the coming years,” said Hecht.
“In my opinion, the IDF needs three more maneuver divisions—but raising them will be very difficult, especially in regard to acquiring the necessary amount of equipment,” he added.
Hecht said that a third lesson is “the need to rebuild the reserves component of the army. The IDF not only reduced their numbers but also deliberately reduced their training—compelling it to retrain many units before employing them because people no longer remembered their skills.”
He highlighted the importance of traditional weaponry, saying the “fourth major lesson is that the weapons of old are still important. During the war, nobody asked for more keyboards and fancy equipment, everybody wanted more tanks, more artillery and more [armored] bulldozers. Some new tools are very useful—especially small drones and quadcopters—and every unit should have them, but they do not change the fundamentals of ground combat. They are an extra capability; they do not replace the veteran capabilities that were reduced because the IDF believed they were no longer needed.”
Finally, he said, Israel will have to adapt to the need to conduct long wars, which require large forces and large ammunition stockpiles, as well as spare parts, accompanied by enhanced wartime production to reduce the dependence on United States aid.
Hecht added that the IDF proved itself highly capable of conducting focused, powerful air-to-ground campaigns, as well as special operations and counter-guerilla operations, but that these do not replace the need for traditional massed ground operations.
Lengthen mandatory service?
On Dec. 5, Army Radio reported that the IDF would be purchasing some 15,000 quadcopters, enlarging its Combat Engineering Corps and creating new infantry units that would have access to advanced armored personnel carriers. In addition, female field observation soldiers will be armed with personal firearms, as part of changes to the ground forces, and observation posts will be moved away from border areas, following lessons learned from the Oct. 7 surprise assault by Hamas.
The IDF is also seeking to lengthen mandatory service to 36 months for most male soldiers to boost personnel numbers. The report said the ground forces have been conducting force build-up processes already during the war over the past year, aimed at creating a larger and better-equipped ground army.
On Nov. 25, the Prime Minister’s Office, Ministry of Defense and Ministry of Finance announced in a joint statement that the Ministerial Procurement Committee approved billions of shekels in procurement and force-building projects for the IDF.
The acquisitions were made in line with the recommendations of the Nagel Committee, which was established in August 2024 to provide consultations on the security budget and the future of Israeli military force building. The committee approved several acquisitions, including the Reshef project—the next navy corvette—as well as the acquisition of hundreds of Joint Light Tactical Vehicles (JLTVs).

‘Totally Obliterated’: US Bombs Iran’s Nuclear Sites, Trump Declares Operation a Success

The United States launched a large-scale military strike against Iran early Saturday, destroying key nuclear enrichment facilities, including the heavily fortified Fordow site.
US President Donald Trump said in a public address that the operation had “completely and totally obliterated” Iran’s nuclear capabilities and urged Tehran to “make peace,” warning that any future aggression would be met with even greater force.
The multi-pronged strike combined stealth B‑2 Spirit bombers deploying bunker-buster bombs with Tomahawk cruise missiles launched from submarines. Fordow, Natanz, and Isfahan — all central to the Iranian nuclear program — were targeted in a coordinated assault. US military officials said the campaign neutralized Iran’s main enrichment operations.
Trump praised Israel’s role in coordinating the response and hailed Prime Minister Benjamin Netanyahu as a key partner, saying the two leaders worked “as a team like perhaps no team has ever worked before.” Netanyahu, for his part, called the American action “unmatched” and said it signaled a shift toward restoring regional stability.
Iran’s foreign ministry condemned the operation as a breach of sovereignty and international law, vowing to respond with force. Hours after the strike, Iran retaliated by unleashing a salvo of roughly 30 ballistic and hypersonic missiles toward central Israel. Several missiles hit urban centers including Tel Aviv, Ramat Gan, Haifa, and surrounding areas, causing injuries to at least 25 civilians and extensive property damage. Israel closed its airspace and instructed residents in key regions to only venture out for essential activities. In response, Israeli jets struck military targets in Iran, including missile launch sites and rocket depots.
Domestically, Trump’s decision exposed sharp political divisions in Washington. Republican hawks applauded the move as decisive, while isolationists and some constitutional conservatives questioned the legality of bypassing Congress, demanding oversight before further military escalation. Meanwhile, the United Nations and key US allies, including Britain and France, urged caution and a swift return to diplomatic solutions.
Iranian state media reported that most nuclear material was evacuated from Fordow ahead of the strike, the Reuters news agency reported. The International Atomic Energy Agency (IAEA), the UN’s nuclear watchdog, said it detected no spike in off-site radiation.
According to Arab sources cited in The Wall Street Journal, the United States sent messages via regional intermediaries to reassure Tehran that the strike was a one-off and not part of a campaign to topple the regime. A senior US official confirmed that the administration clarified it had no intention of pursuing regime change and that the door remained open to renewed negotiations.
US Reps. Thomas Massie (R-KY) and Ro Khanna (D-CA), co-sponsors of a bipartisan resolution to block unauthorized military action in Iran, criticized Trump’s strike as unconstitutional. Massie called the move illegal, while Khanna urged Congress to immediately vote on their Iran War Powers Resolution “to prevent America from being dragged into another endless Middle East war.”
Rep. Alexandria Ocasio-Cortez (D-NY), meanwhile, called for Trump’s ouster, claiming it violated the US Constitution and as such was an impeachable offense.
“The president’s disastrous decision to bomb Iran without authorization is a grave violation of the Constitution and Congressional War Powers. He has impulsively risked launching a war that may ensnare us for generations. It is absolutely and clearly grounds for impeachment,” she said.
Arsen Ostrovsky, a leading human rights lawyer and CEO of the International Legal Forum, rejected the criticism. He said Trump was acting well within his powers under Article II of the Constitution, which grants the president authority as commander-in-chief to protect national security.
“This is not without precedent,” Ostrovsky told The Algemeiner, pointing to former President Barack Obama’s operation to kill Osama bin Laden and former President Joe Biden’s airstrikes on Iranian proxies in Syria.
“Trump did not need the authorization of Congress in order to initiate a military strike,” he said, adding that the action was also supported by the War Powers Resolution of 1973 and Article 51 of the UN Charter, which affirms a nation’s right to self-defense.
Ostrovsky also defended the legality of Israel’s involvement, saying its campaign was not a sudden act of aggression but a response to a protracted armed conflict initiated by Iran.
“Faced with an existential and imminent threat from a nuclear Iran, the Jewish state had no choice but to act before it was too late,” he said. He described the strikes as “lawful, necessary, and proportionate under the Laws of Armed Conflict against a genocidal regime that had vowed to destroy the world’s only Jewish state and stood on the cusp of acquiring the means to do so, had Israel not acted.”
“In striking Iran’s nuclear weapons program, Israel and the United States made the world a safer place. They did it not only in their own defense, but in defense of the free world,” he concluded.

A member of Lebanese armed group Hezbollah was killed in an Israeli air strike on Tehran alongside a member of an Iran-aligned Iraqi armed group, a senior Lebanese security source told Reuters and the Iraqi group said on Saturday.
The source identified the Hezbollah member as Abu Ali Khalil, who had served as a bodyguard for Hezbollah’s slain chief Hassan Nasrallah. The source said Khalil had been on a religious pilgrimage to Iraq when he met up with a member of the Kataeb Sayyed Al-Shuhada group.
They traveled together to Tehran and were both killed in an Israeli strike there, along with Khalil’s son, the senior security source said. Hezbollah has not joined in Iran’s air strikes against Israel from Lebanon.
Kataeb Sayyed Al-Shuhada published a statement confirming that both the head of its security unit and Khalil had been killed in an Israeli strike.
Nasrallah was killed in an Israeli aerial attack on Beirut’s southern suburbs in September.
Israel and Iran have been trading strikes for nine consecutive days since Israel launched attacks on Iran, saying Tehran was on the verge of developing nuclear weapons. Iran has said it does not seek nuclear weapons.
