Welcome to The Logoff: As the Iran war drags on, the US may be running perilously low on key munitions.

What’s happening? According to reporting by Reuters this week, the US has used “virtually all” of its stockpiles of two kinds of precision long-range missiles since the start of the US-Iran war in late February. Its defensive capabilities may be slipping, too. CNN reported on Tuesday that the US has also depleted “nearly 80%” of its supply of THAAD interceptor missiles and around half of its Patriot interceptors.

What do these shortages mean for the Iran conflict? 1) They could limit the US’s military options against Iran. Reporting suggests that this is already happening. According to the New York Times, President Donald Trump decided against a “major escalation” of the US-Iran war late last month after three US troops were killed, at least partially because of concerns about munitions shortages. 

2) The shortage of interceptors increases the danger for US troops and allies in the region. According to the Atlantic, US forces are now at the point where they have to make snap decisions about whether to use an interceptor or ride out an attack. They’re also at a mathematical disadvantage; the US has relatively few interceptors, which cost millions to produce. Iran, meanwhile, can hurl mass-produced drones at the US for about $35,000 each.

How is Trump responding? Not well. The shortages are reportedly causing friction between Trump and Defense Secretary Pete Hegseth, and the president has lashed out on social media. 

“The U.S. has massive amounts of ‘munitions,’ especially of certain types,” Trump posted on Friday. “The ‘leakers’ of these treasonous statements are being hunted down. Long term jail sentences will be sought!”

What’s next? One effect of the shortage could be to encourage an end to the fighting. A new agreement over the Strait of Hormuz between Iran and Oman is reportedly in the works, which could be a step toward ending the war — if the US is willing to make some concessions.

And with that, it’s time to log off…
