Our latest Nuclear Notebook is public: The changing nuclear landscape in Europe. It provides our overview of the nuclear situation, with focus on non-strategic nukes. All the players are increasing their nuclear postures. Check details here: www.tandfonline.com/doi/epdf/10....

Good to see this clearheaded rejection of the Trump regime’s threat to take Greenland. newsletter.ivodaalder.com/p/americas-s...

Condemnation is widespread, also in Europe, but as a narcissistic thug, Trump is not constrained by facts or reasoning but feels reaffirmed to continue.

One of the most dangerous flaws in the US system is that politicians can stack the courts. It undermines checks and balances. Trump is exploiting this flaw to his benefit.

In response to the Trump regime’s threats to take Greenland, the joint statement with France, Germany, Italy, Spain, UK, subsequently endorsed by Netherlands, Canada stm.dk/statsministe..., was accompanied by joint statement from all the Nordic countries: um.dk/en#/embedded...

Five years ago, a violent mob incited by Trump stormed Congress as part of his efforts to overturn the presidential election. He lied about it then, has lied about it ever since, even pardoned the criminals. Reckless voters put him back and he continues to destroy the country.

The Dutch say they also support the statement. x.com/minpres/stat...

Amazing situation where the six large European NATO members (France, Germany, Italy, Poland, Spain, United Kingdom) issue joint statement with Denmark reaffirming Greenland/Denmark autonomy, NATO membership after threat from Trump regime to take Greenland. stm.dk/statsministe...

It is obviously deeply hypocritical that Miller - who otherwise rants about US border protection and immigration “invasion” threat against US sovereignty - dismisses Greenland/Denmark criticism of the Trump regime’s threat to take Greenland. But all he understands is the power.
TAPPER: Can you rule out the US is going to take Greenland by force?

MILLER: Greenland should be part of the US. By what right does Denmark assert control over Greenland? The US is the power of NATO

T: So force is on the table?

M: Nobody is gonna fight the US militarily over future of Greenland

In response to repeated threats from the Trump regime, the Danish government yesterday issued the following statement.

US and Danish adversaries must be having a party. Trump is doing their work for them.

The original statement in Danish is here: stm.dk/presse/press...

A day after Trump attack on Venezuela and abduction of Maduro, the Danish ambassador to the United States reacts to crazy post from wife of Trump advisor Stephen Miller about US takeover of Greenland.

Few in Greenland or Denmark can recognize the United States today.

As Trump chaos grows with Venezuela attack, it will be wild to follow elements of his “plan” unfold:

• “running” the country
• legal “wrath” process against Maduro
• sending US oil in to “fix” Venezuela oil
• war on (some) drugs and immigrants

“peace president,” has just started bombing Venezuela. www.bbc.com/news/live/c5...

Like Putin, Trump needs a war to distract from problems at home. Disgraceful and illegal.

There’s no surprise here; it was never about efficiency but cuts.

Customer service deteriorated by key measures as the agency enacted sweeping cuts in Trump’s second term, internal data and interviews show.

After nearly four years of Putin’s illegal war on Ukraine, Russia is losing soldiers faster than ever, according to BBC study. Of more than one million Russian casualties, between 243,000 and 352,000 are dead. www.bbc.com/news/article...

After Trump regime slashed electric vehicle, renewable energy support, watered down pollution standards, reinforcement, and penalties, electric car sales dropped. But not public support for alternatives to gas pollution. www.npr.org/2025/12/29/n...
Electric vehicles had a bumpy road in 2025 — and one pleasant surprise
A suite of pro-EV federal policies have been reversed. Well-known vehicles have been discontinued. Sales plummeted. But interest is holding steady.

Although the growth of warheads in China’s nuclear stockpile slowed last year, satellite imagery and other information show facilities intended to produce/maintain those warheads have grown. www.washingtonpost.com/world/2025/1...

The Trump regime is ramping up its threat to get Greenland. And the Republicans apparently are fine with this disgraceful behavior of the White House.

Scaled-back Pentagon report on China. Nuke stockpile increase slowed, with 2024 inventory remaining in low-600s. 100+ ICBMs loaded in new silos (no “peer” yet), 50 more DF-26 (anti-ship?), hardly anything on Navy/AF nuke programs. media.defense.gov/2025/Dec/23/...

It used to be that Greenland security was about the Soviet Union. But these days the threat is the Trump regime. The Danish government even has to summon US ambassador. Putin and Xi probably can’t believe their luck there’s such a crook in the White House. www.cnbc.com/2025/12/22/d...

4/4 - Let’s see the plan: cost, shipyards, vulnerability, operational and diplomatic effects. The way we have seen the Trump regime operate, I doubt any critical analysis made it far up the ranks.

3/n - Nuclear-powered warships with nuclear weapons onboard will likely reduce access to foreign ports and turn “good will” port visits into diplomatic irritants. This is a hard-learned lesson of the Cold War. fas.org/publication/...

2/n - The US Navy used to operate a small number of nuclear-powered cruisers, but they were retired and replacements instead built with conventional propulsion because the nuclear ships were too expensive and alleged nuclear benefits not worth the extra cost.

1/n - Strongman Trump has a new me-plan: A so-called “Golden Fleet” headed by nuclear-powered battleships. Yuuuge, “best-looking,” and named after him.

A normal Congress adhering to its constitutional role of checking the executive branch would have lots of questions.

Trump lies about everything, also the reason for his military distraction show against Venezuela. Here is the background: www.washingtonpost.com/world/2025/1...
Trump says Venezuela stole U.S. oil, land and assets. Here’s the history.
The government of the oil-rich nation took control of its petroleum industry in 1976, nationalizing hundreds of private businesses and foreign-owned assets.
www.washingtonpost.com

Trump, who has never lifted a finger for the arts, has added his name to the Kennedy Center. This comes weeks after he added his name to the Institute of Peace, as he masses military off Venezuela.

Soon we’ll probably get the Trump Constitution of the United States.

Rushing nuclear power plant construction with an industry hunting government subsidies and the Trump regime’s disdain for rules and accountability, what could possibly go wrong?
NEW: Trump's new Reactor Pilot Program is rushing to build at least 3 experimental reactor designs by July 4, 2026.
