The article never once acknowledges that, in fact, Trump can’t unilaterally end the war. There’s this small problem that Iran has agency, too. www.nytimes.com/2026/09/27/u...

banning international competition is bad for consumers and it reduces the incentives of local firms to innovative and be more efficient, making them less competitive internationally. Dumb and short sighted.

Israel's Election Committee disqualified all Arab parties today from running in the Knesset elections. I expect the decision to be over ruled by the Supreme Court. Still, shameful vote. "only democracy in the middle east"

Saddened to wake up to the news that my former colleague, Ellen Kennedy died yesterday. Professor Kennedy was an eminent political theorist whose work on Carl Schmitt shaped scholarship on law, constitutionalism, liberalism, and sovereignty. She was a force of good and she will be missed.

At the same time, ~30 states passed laws or executive orders that restrict public entities from doing business or investing with companies that boycott Israel. Only the right is allowed to use the purse as leverage.

The media keeps suggesting that (essentially) social democrats are too radical, but politicians who did not vote to certify the 2020 elections represent total normal politics.

I am no political consultant but I don’t understand why the democratic party is not hammering Trump daily on corruption. Citizens don’t understand the intricacies of “protect democracy” but understand instinctively corruption when they are shown one.

Sadly, horrific as it is, this event would not have gotten such exposure if there wasn't a US citizen involved. Also "the army’s struggle to curtail settler violence" is... misleading at best. The article details show the insane are running that asylum too (as the country, at least until Oct 27).

Israelis, sadly, have grown numb to settlers' violence in the West Bank. But the siege, destruction and terrorization in Qusra in the past few days is so beyond the pale that remaining quiet is not an option. www.nytimes.com/2026/08/12/w...

I don’t agree with all Abdul El-Sayed’s views, but GOP “othering” is a disgrace. He was born in US, educated at Bloomfield Hills Andover, where he captained football team; Univ of Mich; Oxford as a Rhodes Scholar; Columbia, where he earned an MD. Debate his views, not whether he’s a “real” American.

Today, the Israeli media reported a truly bombshell development, which I'd argue, could be hugely consequential, increasing dramatically the likelihood that the "anti-Bibi's" block can form a coalition after the October 27 elections. Sit tight.
