Now that the US is knocked out, I am formally extending an invitation to the American people to support Norway.

Why?

1: The Vikings discovered America before Columbus.

2: There are more ethnic Norwegians in the US than in Norway.

3: Next weekend we can pillage the English peasants together.

Trump watching Iran fire missiles towards Israel after being ready to announce a deal on Monday

[Mike Levin @MikeLevin]

This is really stupid, and it’s not getting enough attention.

The Trump administration is pulling a working $368 million ocean monitoring system out of the water, equipment taxpayers already bought, built, and sank into the deep ocean.

And they are doing it right when the oceans are behaving in ways that alarm the scientists who study them.

Record-breaking temperatures.

A system of Atlantic currents that may be lurching toward collapse.

The response?

Yank out the instruments and walk away.

That is not budgeting. That is smashing the gauges while the engine is on fire and calling it efficiency.

For what? The Trump administration dressed it up as a “nimbler approach” and “smart lifecycle management,” which is fancy nonsense for “we shut it off and hoped nobody would ask why.” There is no return-on-investment analysis. They cannot show taxpayers save a dime, because the gear is already paid for and the science it produces protects real money and real lives.

The kicker: the same people killing the monitors want to mine the deep sea for minerals. So they are destroying the only tools that could measure what that mining does. That is not an accident.

That is the point. You cannot see the damage if you break the instruments first.

In this story we're the visitors from another world.

[ian bremmer @ianbremmer]

no regime change in iran, no handpicking of the next supreme leader.

no dismantling of iran’s proxies, no restrictions on its ballistic missile and drone programs.

an agreement to downblend the highly enriched uranium inside iran.

the destruction of iran’s navy, but an emboldened iran that is prepared to disrupt the strait.

throw in the cost in lives, the global economy, and the global treasure, and the reputational damage to the united states…and president trump has some serious explaining to do.  

next up: cuba

Oil bears lining up to short oil on Trump's fake deal announcement

[Brian Krassenstein @krassenstein]

HOLY CRAP Trump actually accomplished a miracle. Here is what he got out of Iran:

- Reduce its stockpile of enriched uranium by about 98%

- Limit uranium enrichment to 3.67% purity (far below weapons-grade)

- Cut the number of installed centrifuges by roughly two-thirds

- Only enrich uranium at one declared site (Natanz)

- Stop enrichment activities at Fordow and convert it into a research facility

- Redesign the Arak heavy-water reactor so it could not easily produce weapons-grade plutonium

- Ship out or dilute excess enriched uranium
Allow extensive inspections by the International Atomic Energy Agency (IAEA)
Permit continuous monitoring of nuclear facilities and supply chains

- Accept “snap” inspections under expanded monitoring rules

- Avoid building new heavy-water reactors for years

- Stay within strict limits on uranium stockpile size and centrifuge development for set periods ranging from 10–25 years

Ooops, sorry!

That was the JCPOA that Obama signed with Iran, only to have him tear it up, kill 140 kids, get hundreds of Americans injured, 13 killed, and gas prices to surge 50%.

[Dr. M.F. Khan @Dr_TheHistories]

Humanity nearly ended in 536 AD, when the sky turned a permanent shade of bruised violet. This was not a solar eclipse or a passing storm, but a global catastrophe that lasted over a year.

Contemporary historians in the Eastern Roman Empire watched in terror as the sun lost its luster. It provided the illumination of a pale moon, failing to cast shadows even at midday.

In the Mediterranean basin, the warmth simply vanished. The climate shifted so violently that the usual rhythms of life, trade, and survival ceased to function.

Reports from China detailed snow falling in August, destroying the grain harvests and leading to widespread famine. The social order of the northern hemisphere began to fracture under the cold.

For centuries, the cause of this atmospheric shield remained a deep mystery to modern scholars. They saw the collapse of the Dark Ages but could not find the physical culprit.

Recent analysis of ice cores from glaciers has finally identified a massive volcanic eruption in Iceland as the source. Millions of tons of sulfur ash were injected into the stratosphere.

This debris formed an impenetrable layer that reflected sunlight away from the earth for a decade. The cold weakened the human immune system, preparing the world for even greater horror.

When the Justinian Plague arrived in 541, it found a population already decimated by hunger and lack of vitamin D. Nearly half of the Roman population perished in the following years.

We often assume our civilization is permanent, yet a single geological event almost triggered a total human reset. The ice preserves the record of a world that almost stopped breathing.

MAGA when Trump surrenders, gives control of Hormuz to Iran and China, unfreezes BILLIONS in assets, lifts the blockade and lets Iran keep its enriched Uranium:
