My piece in today's @IrishTimes on why State supports for Irish companies aren't working.

Trump U-turns and starts to blame Iran for driving up the cost of diesel, after his plot to blame Ukraine and simultaneously force Kyiv to capitulate to fascist Russia crashes, rolls, burns and explodes. The White House must have felt quite a backlash from American voters, who mostly support Ukraine, not fascist Russia.

Weidel: "Prolonging the war and shooting drones into the hinterland of Russia, destroying refineries, houses, and buildings near Moscow, is a huge provocation."
Host: "It's defending itself."
Weidel: "No, it's not."
Host: "Every night, drones and ballistic missiles rain down on Ukraine..."
Weidel: "This strategy is very risky, and we've been criticizing it. We want to end this war.
It doesn't help if a country [Ukraine] launches drone attacks against a country [Russia] that has nuclear weapons. It doesn't make sense, it's very risky and very stupid.
We need to end this, and we need to actually put pressure on Ukrainian president to have the willingness to end the dying and stop this very risky strategy for all of Europe."🔚
Folks, here is Weidel's imaginary reality: black is white, the victim is to blame for the crime against them, and defending your home against a bloody, illegal invasion that murders children and razes towns is "stupid," while letting Russia occupy you and carry out a country-wide Bucha massacre is probably smart.
And defending yourself is risky! Risky, did you hear that? Well, no shit, just standing there and catching Russian ballistics with your face is risky, too. So we may as well take the risk and, hear me out, fight back?
Please don't vote for this evil Russian appendix in Germany!
Scrap the Electoral College. The presidential election is the one race where we as American citizens vote to decide the direction of the entire nation. We are all equal. No one’s vote in one state should ever count more than someone else’s in another. A candidate can lose the popular vote and still win the White House. Most states get ignored while a few swing states decide everything. A national popular vote would finally match the majority. Still defending an antiquated system that ignores the most ballots?
Unfortunately, this won't work all the time. You'll only get these results when there's an upcoming election.

“What is it mein Fuhrer?”
“It’s from Steve Witkoff. He’s nominated me for the Nobel Peace Prize.”

Wow, the US truly has the most incompetent president in history.
Just listening to how clueless this man is, it’s no wonder we have been humiliated in Iran.
Trump: “The Russians had a thousand tanks riding up a concrete highway. They would have been in Ukraine in four hours, going maximum tank speed, which is 48 miles an hour, to be exact. Nothing to stop them. The war would have been over in one day. And this very stupid general - I have no idea who he is. I doubt he’s still with us. I doubt he’s still living. He decided to hang a right onto the farmland and then take a left and go up to Kyiv, rather than staying on the highway - the concrete highway, perfectly good highway - where they were doing very nicely. It would have been three and a half, four hours, and the whole war would have ended. He ended up getting stuck in the mud.”
Does he understand that Ukrainian troops destroyed all the bridges and cut off the retreat points, so the only option left was to go off the highway? I mean, if you have the IQ of a 10-year-old child, you should be able to get it.
I am honestly shocked at the basic level of ignorance. And this is the man who is in charge of the US Army.

В 1994 году США, Россия и Украина подписали соглашение об отказе Украины от ядерного оружия. Украина отдала 4 400 ядерных боеголовок. Взамен США и Россия гарантировали Украине «независимость и существующие границы».
Спустя 30 лет один гарант напал, а другой требует капитуляции
They don't call him Steve Witless for nothing. What a gobshite.
Witkoff called Putin a humanist as he thanked him for Stephen Hubbard’s release. Russian troops seized the elderly American in Izium, and former fellow prisoners reported that he had been beaten, tortured with electric shocks, burned and attacked by dogs. This is a punitive system created and endorsed by Putin, who is himself a product of that system.
Let us recall some examples of the “humanism” displayed by Putin and the system he created.
Wars. Chechnya, Georgia, Syria, Ukraine—a succession of military campaigns involving mass civilian casualties. In Novye Aldi in Chechnya, Russian forces executed at least 60 people. In Georgia, the European Court of Human Rights (ECtHR) established Russia’s responsibility for killings, torture and the burning of homes. In Syria, human rights organisations documented unlawful strikes by Russian and Syrian forces on hospitals, schools and markets.
His personal decision to invade Ukraine. On 24 February 2022, Putin himself announced the start of the full-scale war. As early as 2014, he publicly spoke of using civilians to shield Russian troops: standing “behind them, not in front, but behind” and challenging Ukrainian soldiers to “try shooting at women and children.”
Killings of civilians and the destruction of shelters and hospitals. Bucha, with its extrajudicial executions; the Mariupol Drama Theatre, marked with the word “CHILDREN”; and the missile strike on Okhmatdyt Children’s Hospital are specific instances of violence committed by the army Putin sent into Ukraine. They have been documented by the UN and international human rights organisations.
The deportation of children. The International Criminal Court (ICC) issued an arrest warrant for Putin over his suspected personal responsibility for the unlawful deportation and transfer of Ukrainian children. The UN Commission of Inquiry classified these practices as crimes against humanity.
Torture and the hunting of human beings. The UN Commission of Inquiry found that the Russian authorities’ systematic use of torture constituted a crime against humanity. It reached the same conclusion regarding systematic drone attacks on civilians in the Kherson region.
Depriving millions of the basic necessities of life. Strikes on energy infrastructure left Ukrainians without electricity, heating and water, and threatened the operation of hospitals. In connection with this campaign, the ICC issued arrest warrants for Shoigu and Gerasimov, including for suspected attacks on civilian objects.
MH17 and the concealment of responsibility. All 298 people aboard the passenger aircraft were killed when it was shot down. The ECtHR established Russia’s responsibility for the disaster and for violations of the rights of the victims’ relatives.
Poisonings abroad. A British inquiry found that Putin had probably approved Litvinenko’s murder with polonium. Another inquiry concluded that he had authorised the assassination attempt on Skripal. Novichok left behind by the perpetrators killed a member of the public—Dawn Sturgess.
The persecution of Navalny. After being poisoned with Novichok, the opposition politician was imprisoned; he died in a penal colony. In 2026, five European countries reported detecting epibatidine in samples taken from him and held the Russian state responsible for his poisoning.
Impunity for those who ordered political killings. Nemtsov was shot dead near the Kremlin. Politkovskaya was murdered on Putin’s birthday after investigating crimes in Chechnya.
Personal support for a state assassin. A German court established that Krasikov had killed Khangoshvili in Berlin on orders from Russian state agencies. Following a prisoner exchange, Putin personally met the convicted murderer at the airport and embraced him.
“Kursk”: 118 dead and “It sank.” In the first days of the disaster, Putin remained on holiday while Moscow delayed accepting foreign assistance. All 118 sailors died. Later, when Larry King asked what had happened to the submarine, Putin replied: “It sank.” His initial response to a question about the deaths of an entire crew took just two words.
“Nord-Ost” and Beslan: contempt for hostages’ lives. In the Nord-Ost case, the ECtHR found that the rescue operation following the use of gas had been inadequately organised. In Beslan, the authorities failed to take appropriate measures despite having information about the threat of an attack. During the operation, security forces used tank guns, grenade launchers and flamethrowers—the court found that this had contributed to the hostages’ deaths.
Children as hostages to political revenge. In retaliation for the US Magnitsky Act, Putin signed a law banning US citizens from adopting Russian children. Even nearly completed adoptions were halted, including those involving children with serious illnesses. The ECtHR found the ban discriminatory and disproportionate. The Kremlin demonstrated its power to Washington at the expense of children who could have found families.
The 1999 apartment bombings: questions the Kremlin cannot brush aside. Hundreds dead, another war in Chechnya and the rapid consolidation of Putin’s power. Litvinenko, Felshtinsky and Satter accused the FSB of organising the bombings. In Ryazan, the FSB later claimed that a device initially regarded as a bomb in an apartment building was part of a “training exercise with sugar.”
Torture, coerced confessions and years of imprisonment—this is how Putin’s government punishes disobedience. Ukrainians, Crimean Tatars and Russian opposition figures have received prison sentences of 10, 20 and 25 years in politically motivated cases.
By calling Putin a humanist, Witkoff grants moral absolution to a ruler who starts wars, presides over a state that practises systematic torture, and personally welcomes a convicted murderer.

Churchill could have shortened WW2 by years if he had just “done a deal” with Hitler. George Washington could have done a deal to end the American Revolution. Zelenskyy is in good company.

The representative of the United States to a warmongering dictator. Speaking like a supplicant and sycophant. Is there any American who does not think this is profoundly un American?

Trump: “russia, frankly, has treated Ukraine pretty well. They haven’t really done much.”
What an absolute piece of shit.

Is it too much to hope that Trump’s betrayal of Ukraine and his sucking up to a murderous dictator who despises all that is good about America will further damage him in the mid-terms rather than, as he hopes, help him? If it is the latter then we really have to wonder whether the problem with America goes a lot deeper than Trump, and will outlive him.
