Gideon Sa'ar | גדעון סער on X: "The Iranian regime's recent actions underscore that its aggression constitutes a direct threat not only to Israel, but to regional and international peace and security.

Israel's non-Article-51 letter to the UN repeatedly refers to "ongoing" Iranian hostilities (or armed conflict), but conspicuously doesn't identify any armed attacks by/ attributable to Iran between last year's ceasefire and the recent attacks by Israel/U.S.

UNICEF says that in just 12 days of war in the Middle East, more than 1,100 children have been reported injured or killed in the violence. “This includes 200 children reportedly killed in Iran, 91 in Lebanon, four in Israel and one in Kuwait.“

This lawless war has to stop.

“The stakes could not be higher. The prohibition on the resort to force in international relations is the keystone of the contemporary international legal system. If it were to fall into desuetude, the consequences would be felt first and foremost in the catastrophic human toll of war.”

If you took $1 billion and gave it to the endowment of a different small college each day, they could each provide a free college education to several hundred students per year in perpetuity. Instead we are using that money to bomb schools and kill students in Iran, for no clearly stated purpose.

On congressional Iran hawks who oppose war powers legislation:

1) Haven't seen any introduce a recent Iran AUMF to authorize this war.

2) Likely b/c they know it would be deeply unpopular & fail. And they don't want to own a vote for war.

3) So they surrender their constitutional power to POTUS.

they knew they could get away with it because they practiced all those times on the “narco-terrorist” boats, where they also killed the survivors, and nobody sent them to The Hague about it so they are running completely unchecked right now with full use of the arsenal. I do not know how this ends

“Almost all the 165 people killed in the attack were girls aged between seven and 12, according to local officials. There were around 170 girls at the school in southern Iran’s Minab at the time.“

A double-tap strike on little girls at school.

So there’s a report on Bluesky this morning that Claude misidentified the school tragically hit in Iran as a military target, except the report is itself sourced to Claude? Am I the one hallucinating now?

President Trump says Iran was "going to attack if we didn't do it" YouTube video by ABC News

People are rightly concerned about the idea that decisions to go to war might turn on the President’s whim, on his opinion, alone, that Iran was “going to attack.”

So glad that the US Congress thoroughly considered and publicly debated the costs of this war before voting to authorize it.

Screenshot from Grotius, De iure belli (Kelsey translation): 
In the second place the fact must not be recognized that our right to wage war is to be regarded as arising not merely from the origin of the war but also from causes which subsequently develop; just as in lawsuits a new right is often acquired by one party after suit has been brought. Thus those who associate themselves with him who assails me, either as allies or subjects, confer upon me the right to protect myself against them also.

In like manner those who join a war that is unjust, especially if they can or ought to know that it is unjust, obligate themselves to make good the expenses and losses incurred, because through their guilt they cause the loss. Similarly, those who join in a war that has been undertaken without a cause worthy of approval draw upon themselves the desert of punishment, in a degree proportionate to the injustice which lies in their actions. For this reason Plato approves of war 'until the guilty are compelled, by the guiltless who have suffered, to pay the penalty'.

"[T]hose who join a war that has been undertaken without a cause worthy of approval draw upon themselves the desert of punishment, in a degree proportionate to the injustice which lies in their action."

The abstract of the article, setting out the general findings.

The strongest arguments against qualified immunity reform are that lawsuit costs would skyrocket and officer retention would plummet. Alex Reinert, Jim Pfander, and I studied qualified immunity reforms in Colorado and New Mexico and can report: the sky is not falling. papers.ssrn.com/sol3/papers....

The UK's legal position on the use of its bases in the Middle East is solid with one glaring hole: The US cannot act in collective self-defence with the Gulf States. It is the aggressor. Ergo the UK cannot assist the US in collective self-defence.

the brilliance of the UN Charter's ban on and conditions for use of force -- legitimate individual or collective self-defense, or Security Council authorization -- is that it challenges governments to justify what is the most devastating use of state power. it's also intuitive.
