Both Israel and the US should ponder air power's limits in Iran
As the war between Israel and Iran escalates, Israel is increasing its calls on the United States to become involved in the conflict.
Former Israeli officials are appearing on US news outlets, exhorting the American public to support Israel's actions.
President Donald Trump has signaled a willingness for the US to become involved in the conflict. He's gone so far, in fact, to suggest in social media posts that he could kill Iran's supreme leader if he wanted to.
The American military could certainly make an impact in any air campaign against Iran. The problem from a military standpoint, however, is that the US, based on its forces' deployment, will almost certainly seek to keep its involvement limited to its air force to avoid another Iraq-like quagmire.
While doing so could almost certainly disrupt Iran's nuclear program, it will likely fall short of Israel's goal of regime change.
In fact, it could reinforce the Iranian government and draw the U.S. into a costly ground war.
The initial stated reason for Israel's bombing campaign — Iran's nuclear capabilities — appears specious at best.
Israeli Prime Minister Benjamin Netanyahu has argued several times in the past, without evidence, that Iran is close to achieving a nuclear weapon. US intelligence, however, has assessed that Iran is three years away from deploying a nuclear weapon.
Regardless of the veracity of the claims, Israel initiated the offensive and now requires American support.
Israel's need for US assistance rests on two circumstances: While Israel succeeded in eliminating key figures from the Iranian military in its initial strikes, Iran's response appears to have exceeded Israel's expectations with their Arrow missile interceptors nearing depletion. Israel's air strikes can only achieve so much in disrupting Iran's nuclear ambitions. Most analysts note that Israel's bombings are only likely to delay the Iranian nuclear program by a few months. This is due to the fact that Israeli missiles are incapable of penetrating the Fordow Fuel Enrichment Plant, which estimates place close to 300 feet underground.
The United States, however, possesses munitions that could damage, or even destroy, the Fordow facility. Most notably, the GBU-57A/B Massive Ordnance Penetrator (more commonly known as a bunker buster) has a penetration capability of 200 feet.
Multiple strikes by said munition would render Fordow inoperable, if not outright destroyed.
The efficacy of air power has been vastly overrated by the popular media and various air forces of the world. Air power is great at disrupting an opponent, but has significant limitations in influencing the outcome of a war.
Specifically, air power is likely to prove an inadequate tool for one of the supposed Israeli and American objectives in the war: regime change. For air power to be effective at bringing about regime change, it needs to demoralize the Iranian people to the point that they're willing to oppose their own government.
Early air enthusiasts believed that a population's demoralization would be an inevitable consequence of aerial bombardment. Italian general Giulio Douhet, a prominent air power theorist, argued that air power was so mighty that it could destroy cities and demoralize an opponent into surrendering.
Douhet was correct on the first point. He was wrong on the second.
Recent history provides evidence. While considerable ink has been spilled to demonstrate the efficacy of air power during the Second World War, close examination of the facts demonstrates that it had a minimal impact. In fact, Allied bombing of German cities in several instances created the opposite effect.
More recent bombing campaigns replicated this failure. The US bombing of North Vietnam during the Vietnam War did not significantly damage North Vietnamese morale or war effort. NATO's bombing of Serbia in 1999, likewise, rallied support for the unpopular Slobodan Milosevic due to its perceived injustice — and continues to evoke strong emotions to this day.
Iran's political regime may be unpopular with many Iranians, but Israeli and potentially American bombing may shore up support for the Iranian government.
Nationalism is a potent force, particularly when people are under attack. Israel's bombing of Iran will rally segments of the population to the government that would otherwise oppose it.
The limitations of air power to fuel significant political change in Iran should give Trump pause about intervening in the conflict.
Some American support, such as providing weapons, is a given due to the close relationship between the US and Israel. But any realization of American and Israeli aspirations of a non-nuclear Iran and a new government will likely require ground forces.
Recent American experiences in Afghanistan and Iraq show such a ground forces operation won't lead to the swift victory that Trump desires, but could potentially stretch on for decades.

Iran: Over 400 killed since start of war with Israel
Iran: Over 400 killed since start of war with Israel Tehran says Israeli attacks have also left 3,056 others wounded. File photo: Reuters Israeli strikes on Iran have killed more than 400 people since they began last week, the Islamic republic's health ministry said in an updated toll on Saturday. "As of this morning, Israeli attacks have claimed the lives of over 400 defenceless Iranians and left 3,056 others wounded by missiles and drones," health ministry spokesman Hossein Kermanpour said in a post on X. Several "powerful explosions" were heard in the afternoon in southwestern Iran's Ahvaz, the daily Shargh reported, as Israel's military said it was conducting strikes on "military infrastructure" in the area. Ahvaz is the capital of Khuzestan province, which lies on the Iraqi border and is Iran's main oil-producing region. "Fighter jets are currently striking military infrastructure in southwestern Iran," the Israeli military said in a statement. The country's military also said it had killed a top Iranian official in charge of military coordination with the Palestinian militant group Hamas, as well as two other Iranian commanders overnight. Earlier, Israeli rescue services said an Iranian "drone strike hit a two-storey residential building in northern Israel" following a wave of attacks reported by the military. Meanwhile, Iran's Foreign Minister Abbas Araghchi arrived in Istanbul for a meeting with regional diplomats to discuss Tehran's conflict with Israel. Around 40 diplomats are due to join the weekend gathering of the Organisation of Islamic Cooperation, as Israel and Iran continue to exchange attacks. (AFP)

VP Vance says US troops still 'necessary' in LA
VP Vance says US troops still 'necessary' in LA California officials have heavily criticised US President Donald Trump over his use of the military, saying it escalated protests. Photo: Reuters US Vice President JD Vance has said that the thousands of troops deployed to Los Angeles this month were still needed despite a week of relative calm in the protest-hit city. US President Donald Trump has sent roughly 4,000 National Guard members and 700 Marines, purportedly to protect federal property and personnel, after demonstrations over immigration raids. "Unfortunately, the soldiers and Marines are still very much a necessary part of what's going on here because they're worried that it's going to flare back up," Vance told reporters in Los Angeles. He was speaking the day after an appeals court ruled that Trump could continue to control the California National Guard, which would normally fall under Governor Gavin Newsom's authority. California officials have heavily criticised Trump over his use of the military, saying it escalated protests that local law enforcement could have handled. The demonstrations were largely peaceful and mostly contained to a small part of Los Angeles, the second-largest US city, although there were instances of violence and vandalism. "If you let violent rioters burn great American cities to the ground, then, of course, we're going to send federal law enforcement in to protect the people the president was elected to protect," Vance said, adding that Trump would deploy them again if needed. The Republican further accused Newsom – a possible contender for the Democratic presidential nomination in 2028 – and Los Angeles Mayor Karen Bass of encouraging protesters. Newsom and Bass have both condemned rioting and violence towards law enforcement while accusing the Trump administration of manufacturing a crisis in the city. (AFP)

Israel says Iran's supposed nuclear programme delayed by 2 years amid fresh attacks
Israel claimed on Saturday it has already set back Iran's presumed nuclear programme by at least two years, a day after a warning by US President Donald Trump of a 'maximum' of two weeks for Tehran to avoid possible American air strikes. Advertisement Trump has been mulling whether to involve the US in Israel's bombing campaign, indicating in his latest comments that he could decide before the two-week deadline he set this week. Israel said Saturday its air force had launched fresh air strikes against missile storage and launch sites in central Iran, as it kept up a wave of attacks it said were aimed at preventing its rival from developing nuclear weapons – an ambition Tehran has denied. 'According to the assessment we hear, we already delayed for at least two or three years the possibility for them to have a nuclear bomb,' Israel's Foreign Minister Gideon Saar said in an interview published on Saturday. Saar said Israel's week-long onslaught would continue. 'We will do everything that we can do there in order to remove this threat,' he told the German newspaper Bild. Advertisement Top diplomats from Britain, France and Germany met their Iranian counterpart, Abbas Araghchi, in Geneva on Friday and urged him to resume talks with the US, which had been derailed by Israel's attacks.
