Russians target and kill civilians because Russians are terrorists.
Ukraine defends herself by hitting Russian military and economic targets.
The difference speaks volumes. Slava Ukraini 🇺🇦

The isolator helmet was a device invented by Hugo Gernsback in 1925 to help people concentrate and eliminate distractions. The helmet was made of wood and felt, and had three pieces of glass that allowed the wearer to see only a narrow slit in front of them.
The helmet also blocked out all sounds, and had a tube that supplied oxygen to the wearer. The idea was that by isolating the senses, the wearer could focus better on reading or writing.
However, the helmet also had some drawbacks, such as making the wearer drowsy after 15 minutes, and being very bulky and uncomfortable. Gernsback claimed that the helmet was 90-95% efficient in blocking out noise, but he only made 11 helmets and they disappeared by 1926. The isolator helmet was featured in Gernsback’s magazine Science and Invention, and later inspired other similar devices such as the Helmfon.

.@SenatorSlotkin on Iran & Russia: "There's press reports that the Russians are helping target U.S. ships and aircraft… If Russia is helping to kill U.S. forces, we have crossed a Rubicon…We have to take decisive action on that, and instead, we're giving them breaks on oil."

Frank White gave astronauts the language to explain what they could not put into words.
He called it the Overview Effect.
Now it's our turn to send him to space so he can experience it directly, and you can fly alongside him.

This is so beautiful!
Ukrainian drones destroyed one of the largest oil hubs in southern Russia, the Tikhoretsk oil pumping station.
The facility serves as a major oil depot and transshipment terminal located in Russia’s Krasnodar region, through which large volumes of oil are transported.

We have just proven that we can deflect asteroids.
Ever since @NASA crashed the DART probe into this asteroid's little moon, we've been tracking the result. Now we know its 770-day orbit around the Sun changed by a fraction of a second.
That's enough to defend our Earth. The dinosaurs wish they'd had a space program!

Solar accounted for 54% of all new electricity-generating capacity added to the US grid in 2025.
Combined, solar and storage made up 79% of new capacity last year.
China has significant growths in solar capacity and generation — the US must be doing the same.

Today, my meeting with the President of Romania, @NicusorDanRO, focused primarily on strengthening the energy and economic capacities of both our nations so that together we can do more for the national security of our states.
We are working to expand cross-border energy cooperation – building two new power transmission lines with Romania. Equally important is our ability to pursue projects together in resource extraction on the Black Sea shelf. Today, we also discussed projects in the oil and gas sector that can support us now, including in light of the challenges related to the Middle East. We reviewed opportunities for transporting American LNG to Ukraine via Romania. We are also working to open new border crossing points – and this will be achieved already this summer.
I thank Romania for its principled position throughout all these years of Russia’s full-scale war. Ukraine and Romania are natural strategic partners. The geography of our region, the security challenges we face, and the economic needs of our peoples all point to one conclusion: cooperation between us must only grow stronger.

BREAKING: Saudi Aramco, the world’s largest oil company, is negotiating to buy drone interceptors from Ukraine, the country Russia has been bombing for four years, to defend its oil fields from Iran, the country America has been bombing for two weeks.
Read that sentence as many times as you need. It is the 21st century in a single transaction.
The Wall Street Journal reports that a Saudi intermediary closely tied to Aramco is in advanced talks with Ukrainian manufacturers SkyFall and Wild Hornets for their P1-SUN and STING interceptor drones, plus Phantom Defense electronic warfare systems, in a multi-million-dollar batch purchase explicitly designed to destroy Iranian Shahed-type drones before they reach Saudi oil infrastructure.
Ukraine learned to kill Shaheds by being hit with them. Russia has launched thousands of Iranian-made Shaheds at Ukrainian cities, power stations, and military positions since 2022. Ukrainian engineers did not study the Shahed in a laboratory. They studied it falling through their bedroom ceilings. They reverse-engineered the threat, built interceptors calibrated to its exact flight profile, radar signature, and thermal characteristics, and fielded them under fire. The interceptors work because the engineers who built them did so while the drones they were designed to kill were attacking their homes.
Now Saudi Arabia wants to buy that knowledge. Not from Lockheed. Not from Raytheon. Not from the Patriot system that costs $3 million per missile and was designed to kill ballistic warheads, not $20,000 drones. From Ukrainian startups that built their products in basements and tested them on battlefields.
The strategic implications cascade across every domain this war touches.
For Ukraine, this is the moment the country transforms from victim to vendor. Zelensky’s government has spent four years asking the world for weapons. It is now selling them. Every interceptor drone that ships to Saudi Arabia funds Ukraine’s own defence, reduces Kyiv’s dependence on Western aid, and demonstrates that the country the world pitied has become the world’s most experienced counter-drone power. The “salesman of the year” meme circulating on X understates it. Ukraine is not selling products. It is selling survival expertise, and the market for survival expertise in a world of $20,000 drones is every country with infrastructure worth protecting.
For Saudi Arabia, this is an admission that the most expensive Western air defence systems in the world cannot efficiently kill the cheapest weapons in the world. The Kingdom operates Patriot batteries, THAAD interceptors, and an integrated air defence architecture that costs tens of billions. Against ballistic missiles, these systems perform. Against saturation swarms of $20,000 Shaheds, they are economically irrational: a $3 million Patriot missile destroying a $20,000 drone is a 150-to-1 cost inversion that the attacker wins by firing. Ukraine’s interceptors cost a fraction of Western missiles and are purpose-built for exactly the threat Iran is deploying. Aramco is not buying Ukrainian because it is fashionable. It is buying Ukrainian because the math demands it.
For Iran, this is the beginning of the end of the Shahed’s strategic advantage. The drone that closed Hormuz, burned Salalah, struck the SafeSea Vishnu, hit towers in Dubai, and terrorised Gulf capitals for two weeks is about to face a countermeasure designed by the people who have been fighting it longest. If Saudi fields are protected by Ukrainian interceptors calibrated to the Shahed’s exact signature, the IRGC’s cheapest and most effective weapon becomes progressively less effective with every unit deployed.
For the world, this is the moment the drone age produces its own antibody. The same battlefield that created the threat created the cure. Ukraine is the immune system the Gulf is purchasing.

Kostiantynivka, Donetsk region.
Russian forces are wiping a Ukrainian city from the map. Homes and innocent lives destroyed.
Absolutely horrific.

The Moon fundamentally changes the game for manned space exploration.
It is a next-level proving ground where astronauts can build habitats, harvest propellant and minerals from the lunar surface, and learn the skills necessary to go onto Mars.

China decarbonising transportation systems faster than any other nation:
electric cars: 34% sales EVs in July, 2/3 world's #EVs
electric buses: 84% bus fleet EVs (600k/712k buses)
electric car chargers: 1 charger/8 EVs
42,000km high speed rail
Repeat after me: we don't need oil
EVs make first visible dent in gasoline consumption USA
EVs don't guzzle fuel - EVs lower energy consumption
Miles driven by vehicles rebound post-covid - but not consumption of oil-based fuels as EVs take fleet share
