Donald Trump has been cautioned that America’s supply of missiles and interceptors could be severely depleted if a conflict with Iran extends over time, according to informed sources.

Military insiders have expressed concerns that a prolonged and resource-intensive conflict with Iran might leave U.S. targets vulnerable, particularly if Iran’s missile and drone capabilities are not swiftly neutralized. This information, reported by the Wall Street Journal, reflects the urgency of the situation.

The report draws on insights from current and former military officials, who have noted the toll that engagements with Iran and its Middle Eastern proxies have taken on the U.S. missile arsenal. This includes vital resources like air defense interceptors and Tomahawk cruise missiles.

Saturday’s strikes marked the beginning of an intense effort to dismantle Iran’s missile capabilities before the U.S. exhausts its supply of interceptors needed to defend against potential retaliatory attacks.

While the exact numbers of the U.S. missile and interceptor reserves remain classified, the recent large-scale strikes on Tehran and other cities underscore the critical importance of this issue.

Reportedly, a senior official mentioned that Trump’s decision to initiate these strikes was strategically aimed at crippling Iran’s capacity to launch a counterattack using its own missiles and drones.

Trump indicated in a call with the Daily Mail on Sunday that he believes the conflict could last as long as a month, and said on Truth Social on Saturday that it will ‘continue, uninterrupted throughout the week or, as long as necessary to achieve our objective of PEACE THROUGHOUT THE MIDDLE EAST AND, INDEED, THE WORLD.’ 

The killing of Ayatollah Ali Khamenei has thrown the conflict into chaos, with sources telling the Associated Press on Sunday that Iran’s leadership is ‘open’ to negotiations. 

President Trump was warned that the US military’s stockpile of missiles and interceptors could run dry if his war in Iran is prolonged for an extended period of time, sources say

With next steps uncertain, US forces said their efforts to block Iranian strikes had been largely successful, although some strikes got through defenses in neighboring nations. 

Kelly Grieco, a senior fellow at the Stimson Center think tank who used to teach at the Air Command and Staff College, told the Wall Street Journal that with more strikes and interceptions likely, the size of the US stockpile may become a factor. 

‘One of the challenges is you can deplete these really quickly,’ Greico said. ‘We’re using them faster than we can replace them.’ 

Among the most vital pieces of weaponry in the US arsenal is the Thaad antimissile system, which are stationed across the globe to monitor and track potential incoming fire. 

Military insiders said keeping stocks of the Thaad’s weaponry high is vital, with the systems also set up outside of the Middle East such as in South Korea and Guam, to deter North Korea and China. 

Replacing the military’s stocks of Patriot and Standard Missile (SM) weapons has also taken priority amid the heightened tensions in the Middle East, with only the SM-3 missiles able to intercept ballistic missiles above the Earth’s atmosphere.

The Journal reported that generals are concerned about the US stockpiles beyond just air-defense interceptors, as the US is also quickly using its supplies of Tomahawk cruise missiles and aircraft-launched weapons. 

Becca Wasser, a senior fellow at the Center for a New American Security, told the outlet that the Trump administration has used weaponry at a high rate in the past year, including the use of long-range precision weapons against Yemen-based Houthi militants.

Iran retaliated to the US and Israeli strikes with a barrage of missiles at neighboring nations – some of which broke through air defense systems (seen in Dubai) 

‘The Trump administration has fired TLAMs (Tomahawk Land Attack Missiles) at an extraordinary rate in operations around the globe, in the Middle East against Iran and the Houthis as well as in Nigeria on Christmas Day,’ Wasser said. 

The military expert said the US will be looking at potential future wars as it chooses how to use munitions in Iran, as she cited the chance of a war with China. TLAMs are powerful missiles capable of devastating infrastructure. 

‘When we wargame, TLAMs are some of the first munitions to go within that first week of a U.S.-China conflict,’ she said.

It comes as the US Central Command said Sunday that three US servicemen had been killed in the strikes on Iran. 

In an exclusive phone interview with the Daily Mail, Trump broke his silence on the deaths and paid tribute to the victims as ‘great people.’

‘And, you know, we expect that to happen, unfortunately. Could happen continuous – it could happen again,’ Trump added. 

Trump acknowledged that the three casualties were the first in his second term, as the January capture of Venezuelan dictator Nicolas Maduro and the June bombing of Iranian nuclear facilities were pulled off without a single American death.

‘We’ve done pretty well,’ he noted, adding, ‘But they’re great people, with outstanding records, outstanding.’

Trump also revealed a potential timeline for the war with Iran – suggesting fighting could go on for the next four weeks.

‘It’s always been a four week process. We figured it will be four weeks or so. It’s always been about a four week process so – as strong as it is, it’s a big country, it’ll take four weeks – or less,’ the President explained.
