If this indeed represents a moment when Trump is trying to end the Iran war, it should be noted that the only state to benefit from all this was Russia. Higher fuel prices, sanctions relief, Belarus rehabilitated, and a pro Russian government still in Iran. Funny that.

I pressed send on this piece before Trump announced his ceasefire of sorts. I went ahead and updated it. What Trump has done strongly supports the central argument of the piece. The US does not want regime change in Iran and might be pursuing the worst example of “mowing the grass” in history.

Just sent out this piece. In the constant changes and instabilities surrounding US victory goals against Iran, one thing is clear. The Trump administration is attempting a US version of "mowing the grass". This is probably the worst strategic concept of my life.

Hi All, Just sent out my free weekend update. It starts with the Ukrainians claiming to have inflicted record Russian losses this week (twice) while keeping Ukrainian down. The Ukrainians seem to think that their way of fighting is superior to western analysts.

Great threat. Knocking out power would eliminate the population’s ability to communicate and organize, which is what people need to coordinate an uprising.

It is a fool's game to say who will end up "winning" this war. Yet, if you are the USA/Israel and planned it, started it, and more than three weeks into it are undertaking an unexpected escalation while relaxing sanctions on Iran--that is hardly a sign of victory at this time.

Highly recommended piece by
@phillipspobrien.bsky.social
on what the Iran war means for a war against China. Russia lost the "Moskva" in a war against a nation without a navy and had to withdraw most of its fleet from Crimea. That is basically the position of the US Navy in a war with China.

New piece. The US campaign against Iran has revealed one major story which people are not acknowledging. For reasons of both internal US weakness and technological development, the US is showing it has almost no chance in a war against China in the Western Pacific.

Very disappointed by the

It is fascinating that as Trump threatens and insults US allies to try and get them to get him out of this ridiculous strategic bind, he does not have the courage to even ask Putin politely to stop helping Iran kill American soldiers. Interesting that.

So, the USA has "100%" destroyed Iranian military capacity, and totally won the war (4 times at least), and, after all that winning, Trump is "demanding" other countries come in to "help us". Yeah, its going well, really well....

This Trump tweet is a work of art and needs to be kept for posterity. It turns out that the US has destroyed 100% of Iran’s military capability. Yet, to combat a military with no capability he is left pleading with allies he has regularly insulted to save him in the Gulf.

Let me see if I get this right. Trump starts a war with no clear strategic aims Trump fails to anticipate Iran choking off the Persian Gulf Trump bombs such that the Iranian people are keeping their head down. And Trump apologists say the problem is Trump critics are mean and won’t support him.
