Hitler killed himself and Germany surrendered. Japan got nuked. Do they teach history in Ohio?
JD Vance: If you go back to WW2 or every major conflict in human history, they all ended with some kind of negotiation.
Community note
World War II ended with unconditional surrenders by Germany on May 8, 1945, and Japan on September 2, 1945, rather than negotiation. en.wikipedia.org/wiki/Unconditi… archives.gov/milestone-docu… nationalww2museum.org/war/topics/end…

We look at our neighboring worlds and we see a grim warning. Venus is a runaway greenhouse hellscape, its surface hot enough to melt lead. Mars is a frozen, bone-dry desert. Earth is the anomaly,a perfectly balanced, delicate jewel where the conditions for life are miraculously just right. Yet, we continue to treat our atmosphere as if it were an infinite dumping ground. A fragile canopy. A destabilized climate. A global crisis.

The idea vaccines cause autism was invented by Andrew Wakefield in 1998 and was so thoroughly debunked he lost his license for gross malpractice And here we are 27 years later RFK Jr dredging up the same nonsense Such a tiresome waste of time

The idea that “natural = good” falls apart the moment you learn what nature actually is. Arsenic is natural. Botulism is natural. Smallpox was natural. Insulin, vaccines, and clean drinking water are not. Nature doesn’t care if you live. Science does.

The post above is an example of Holocaust denial. See our page debunking many deniers’ lies. stopdenial.auschwitz.org Learn about strategies employed by Holocaust deniers to spread misinformation and falsehoods. Online lesson: lekcja.auschwitz.org/negacjo… Podcast: auschwitz.org/en/education/e… Denial of the existence of gas chambers is a disgraceful assault on the memory of all those people: Jews, Poles, Roma, Soviet prisoners of war, and all other victims. It is also a slap in the face to those prisoners who risked their lives to document and convey the truth about German crimes, as well as to the Survivors who still bear the trauma of their personal experiences. Holocaust denial has nothing to do with the truth. It is a mendacious conspiracy theory. A dangerous & hideous carrier of antisemitism & hatred that hurts people. Deniers harass & insult the memory of the victims.

The low IQ individual is Trump, who by the way lacks all civility.
Trump: “Stephen A. Smith is an arrogant fool, a low IQ individual. In other words, he's "dumb as a rock…”

It's worse than that, Trump is one of the most dangerous things in the world...an idiot that thinks he's smart.
Give us a break! Trump has no IQ, and he is president.

What a rotten, braindead party that requires all of its members to tell the same absurd, destructive lie to the American people.
RAJU: But what evidence is there to prove the California election is rigged? MIKE JOHNSON: Look, some of these efforts are so diabolical and so far upstream it's impossible to prove. But I think everybody knows instinctively that something is wrong here.

Ummm...a reporter trying to get the facts?
What kind of despicable person repeatedly talks over and interrupts the President of the United States who gave them the privilege of an interview?

This is unhinged. If a family member behaved this way, you'd worry about them. If a CEO behaved like this, the board would meet. He's living in an alternate reality and furious when a person won't indulge his fantasies.
WOW -- Trump crashes out and cuts his interview with Welker short as she presses him on his lack of evidence for claiming elections are rigged "You're either crooked or you're stupid. Let's call it quits. Because I've had enough. Thank you darling," he tells her." "I traveled all the way to Wisconsin for this interview," she pleads.

I couldn't agree more. In Peru, packs of semi-wild dogs are everywhere. They looked askance at me when I asked why there were no cats..."the cats are in the house". I also shouldn't have to clean cat shit from others cats from my garden 😤. irishtimes.com/life-style/pe…

I’m not sure what the bigger disgrace is, the Vice President of the United States’ ignorant, anti-British bigotry or the journalists of my generation quite happy to encourage him.
Well said.

Spare us the civilisational lectures, you charlatan. Atatiana Jefferson, 2019. Shot dead through her bedroom window during a welfare check. Playing video games with her eight-year-old nephew. The officer never identified himself. Botham Jean, 2018. Shot dead eating ice cream in his own apartment by an off-duty officer who "thought it was her apartment". John Albers, 2018. Seventeen years old. His friends called police because he was suicidal. Officers killed him during the welfare check. Parkland, 2018. Seventeen children and staff massacred in their school. The armed officer paid to protect them? Hid outside. Shajarah Tayyebeh Elementary School, Minab, February 2026. At least 175 dead, most of them girls aged 7 to 12. NYT analysis and US military investigators believe American forces struck the school. Trump blamed Iran without evidence. US Senators are still waiting for answers. In 2025, American police killed 1,201 people. 98 unarmed. 233 school shootings at K-12 schools. American children do active shooter drills in primary school. American families are afraid to call for welfare checks because officers shoot the people they're sent to help. Henry Nowak's father said: "We do not want Henry's murder to be used to create further hatred, division or tension". You used it anyway, to lecture a country 3,000 miles away while your administration bombs schoolgirls and your officers shoot people through bedroom windows. The UK's government has plenty to answer for. But we don't take civilisational lectures from those who run a country that can't keep its children alive in their own classrooms and in their own homes and bomb children in far away lands, you pathetic charlatan.
Henry Nowak died the same way a civilization dies: abandoned, handcuffed by authorities who neither trusted nor cared for him, and accused of hate crimes he did not commit. His murder is as tragic as it is enraging. He should still be alive today, and he would be if the last few generations of European elites had stood their ground against the politics of self-hatred and the mass invasion of migrants, many of whom despise the West and the people who love it. Henry was far from the first to so needlessly lose his life, and I fear he won’t be the last. Each time a life like his is lost, the proper response—the only response—is righteous anger. One of the most important things the Trump administration has proven to the world is that stopping the flow of mass migration and defending national sovereignty is a matter of political will and leadership. Anything else is an excuse. It is because we love the West that we want to preserve it. We love our civilization. We love our country. We love our children. And nobody—nobody—should ever die the way that Henry Nowak died. May God comfort those who loved him, and may God rest his soul.

It's not just the exploitation of a tragedy. JD Vance's picture of Britain - where migrants have led to a crime surge - is the opposite of the truth. comment.press/vance1234

Wasn’t her husband assassinated in broad daylight here in the U.S. while Trump was president?
Erika Kirk says Europe is no longer safe as it has surrendered to criminals, while the US is safe under Trump.
