Our new study provides rare causal evidence about NYC’s speed camera program. We find large reductions in collisions (30%) and injuries (16%) near intersections with cameras. www.pnas.org/doi/abs/10.1... @astagoff.bsky.social ky.social @brendenbeck.bsky.social nbeck.bsky.social 🧪

Trump's national security strategy is out and some of the Europe sections are shocking. "...the growing influence of patriotic European parties indeed
gives cause for great optimism."

No surprise I guess, but the new Trump National Security Strategy does not condemn the Russian invasion of Ukraine nor list upholding the territorial integrity of states as a key priority for the US in Europe.

The strategy of trying to change Putins mind has not worked. Time to shift to a new strategy focused on changing Putins capabilities. That means more and better weapons for Ukraine and more and better sanctions for Russia.

Aimed to read it. But maybe should reassess …?

And in other words, they’re NOT “literally fighting over a 30-50 km strip in Donetsk” as Rubio claims

Over many years, in both words and actions, Russia has made it crystal clear that its goal is conquest, with the destruction of Ukraine’s freedom and independence.

But with a US government intent on lying about that and trying to get Russia a win, it must be repeated.

Ukraine already tried giving up land for Russia’s word to stop attacking, with the Minsk Agreements of 2014-15. Russia violated them with a full scale invasion in 2022.

Why would Ukraine think land for peace would work this time, especially when a Putin-sympathetic US won’t do security guarantees?

This is an actual thing Putin said today:

"We are taking a surgical approach with Ukraine, very carefully."

“Russian President Vladimir Putin has underlined his true intentions by issuing a presidential decree calling for an escalation in efforts to eradicate all traces of Ukrainian identity from the approximately 20% of Ukraine currently under Kremlin control.”

In the running for greatest human accomplishment.

While "peace" negotiations continue, remember that Russia could simply stop the war at any time.

Four people dead, and 22 injured.

OTD in 2021 Russian Embassy on Londonograd reported that US & UK were manipulating false claims of a Russian invasion & occupation of Ukraine to spread panic.

Which is why you can believe us now we say we want peace.

WSJ Gentry Beach, a college friend of Donald Trump Jr. and campaign donor to his father, has been in talks to acquire a stake in a Russian Arctic gas project if it is released from sanctions. Another Trump donor, Stephen P. Lynch, paid $600,000 this year to a lobbyist close to Trump Jr. who is helping him seek a Treasury Department license to buy the Nord Stream 2 pipeline from a Russian state-owned company.

One sign that he may be serious is that some of his most-trusted friends, sanctioned billionaires from his St. Petersburg hometown-Gennady Timchenko, Yuri Kovalchuk and the Rotenberg brothers, Boris and Arkady-have sent representatives to quietly meet American companies to explore rare-earth mining and energy deals, according to people familiar with the meetings and European security officials. That includes reviving the giant Nord Stream pipeline, sabotaged by Ukrainian tactical divers, and under European Union sanctions. Earlier this year, Exxon Mobil met with Russia's biggest state energy company, Rosneft, to discuss returning to the massive Sakhalin gas project if Moscow and Washington gave the green light.

Extraordinary WSJ reporting today that unveils the extent to which Trump, Witkoff, Kushner and US business executives are salivating over business deals with Russia while Putin’s forces kidnap Ukranian children and bomb civilians in their apartments.

Guess.

Lopez Belloza made it through security but was stopped as she was about to board the plane, Pomerleau said. "They wouldn't tell her why she was being detained. She didn't understand it at all," Pomerleau said. She was then taken to the Burlington ICE field office, then flown to Texas, Pomerleau said. The Department of Homeland Security and Babson College did not immediately respond to a request for comment. After a frantic 48-hour search, her family received a call from her on Saturday from Honduras, a country she had not lived in since she was a child. The federal government had quickly deported her, the lawyers said, and Lopez Belloza had found her way to her grandparents' house and called her father.

Imagine getting ready for your daughter to come home from her freshman year of college for Thanksgiving, and the day of departure she goes MIA, and then 48 nightmarish hours later she calls you to tell her that ICE goons kidnapped her and shipped her to Honduras www.bostonglobe.com/2025/11/25/m...

Ukraine is in Europe. And he’s attacking it every day.

the real question is how long russia can keep jangling keys in front of trump's people

What Is Steve Witkoff Trying to Do? Trump’s envoy isn’t promoting peace. His interventions are helping Vladimir Putin and prolonging the war.
