In a recent visit to Greece, the secretary of state suggested that Europe must rediscover the values of conquest and expansion

They had obviously worked hard on the backdrop – and it was magnificent. On 7 October, the US secretary of state, Marco Rubio, delivered a major speech in Athens, outdoors, with the Acropolis behind him. The sun was setting, bathing the ancient scene, including the Parthenon, in the light of the golden hour.

The golden hour, but yet not quite the golden age. This was not Pericles defending democracy. Instead, Rubio offered a haunting vision of the choices facing the west, arguing that the US and Europe must rediscover the values of exploration and conquest that once drove centuries of expansion, or face decline and irrelevance.

Senior official says president and US secretary of state are ‘extremely pissed off’ by conduct of US envoy to Greece

Donald Trump and Marco Rubio, the secretary of state, are considering firing US ambassador to Greece Kimberly Guilfoyle after a series of reports alleging she has engaged in improper and possibly illegal conduct before and during her tenure in Athens.

A senior US official said Sunday that Trump and Rubio are “extremely pissed off” by Guilfoyle’s reported conduct and would likely decide on what action to take this week after Monday’s federal holiday.

A fuel deal with Vladimir Putin, and sanctions against the legal institution, ram home the president’s belief that might is right

On Friday, Donald Trump drove home his belief that might is right and the rule of law is an obstacle rather than an essential foundation stone of international order. First came the escalated assault on the international criminal court (ICC), sanctioning the body itself. Then he announced a deal with Russia to buy diesel.

The US has long chafed at the notion of being bound by the rule of law that it espoused publicly. That hypocrisy now appears as a lesser vice. The president has declared that “my own morality” is all that constrains him. His brazen flouting of the law, embrace of dictators and rhetorical attacks all undermine global standards.

This is no scoffing matter. The accelerating proliferation of advanced nuclear weapons is bringing ‘end times’ closer by the day

Humankind has fearfully and sometimes joyfully anticipated the end of the world ever since it began. The Bible’s Book of Revelation speaks of “end times”, a period of tribulation, war, famine, plague, floods and environmental catastrophe that may seem a less absurd prospect today than perhaps it once did. Islam, too, posits a fateful day of judgment or day of reckoning. Christian evangelicals believe that, in the final rapture, a chosen few – the righteous or the “elect” – will be saved while sinners burn. It’s a minority view. Matthew’s gospel predicts most people will defy, ignore or ridicule warnings of imminent Armageddon. Peter, another of Jesus’s disciples, agreed: “In the last days, scoffers will come, scoffing and following their own evil desires.” Yet such worldly scepticism does not mean a universal cataclysm is less likely. It may make it more probable.

Donald Trump’s blanket denials of the dangers ostensibly posed by artificial intelligence, whose uncontrolled development is seen by some as the latest harbinger of apocalypse, could be interpreted as fulfilling Peter’s prophecy. This US president, the nearest thing the world has to a one-man doomsday machine, is a great one for scoffing and evil desires. In Robert Harris’s 2019 novel, The Second Sleep, a worried scientist lists half a dozen ways the world might end. They include devastating climate change, pandemic disease, a giant asteroid collision with Earth, or some other overwhelming calamity. Few heed the fictional scientist’s fears. In the event, what destroys him and almost everybody else is a disturbingly plausible cyber crash – a global digital and internet meltdown.

David McCloskey’s new book depicts a calamitous collapse of the ‘special relationship’ – could things get darker still?

The “special relationship”, the time-honored emotional bond between the US and Britain that has sustained through war and peace, is in trouble.

The ties of history, culture and language that have bridged an ocean and bound the two countries politically for generations are fraying as perhaps never before – strained relentlessly by Donald Trump, who has gleefully sacrificed traditional alliances and diplomatic niceties on the altar of his “America first” agenda.

US president suggests Ukrainian president, Volodymyr Zelenskyy, has not done enough to end war

Donald Trump has said Ukraine needs “a new leader”, a day after making a deal with Vladimir Putin to buy large quantities of Russian diesel.

The US president suggested Volodymyr Zelenskyy has not done enough to end the war with Russia and blamed him for high diesel prices in the US.

Dozens of CIA officers have been afflicted by debilitating symptoms over the past decade. Are they the result of ‘mass hysteria’? Or are they from attacks with an energy weapon and, if so, who is responsible? And has there been a cover-up?

Shortly after 1am one night in April 2019, a CIA officer on a work trip to London was jolted awake in his hotel room by the most intense head pain he had ever experienced. His body was soaked with sweat and he felt like his eyes were spinning in their sockets. He manoeuvred his way out of bed, hoping to make it to the bathroom to vomit, but found his sense of balance had deserted him. Eventually, he fell back into a fitful, shallow sleep.

The next day, arriving at the work meeting he had travelled for, the officer found he could not remember the names of colleagues in the room, people he knew well. As the meeting got under way, he could barely follow the discussion. Initially, he chalked it up to a terrible – if rather odd – case of food poisoning. But over subsequent weeks, worrying symptoms persisted: brain fog, loss of balance and increasingly harsh tinnitus.

US president says agreement needed to lower fuel prices, but move likely to create fresh crisis with Ukraine and Nato allies

Donald Trump is on a fresh collision course with Volodymyr Zelenskyy and European allies after his stunning agreement to buy Russian diesel upended years of US and western pressure on the Kremlin to end its war against Ukraine.

Zelenskyy reacted furiously to Trump’s announcement of the deal with Vladimir Putin on Friday, calling it “absolutely terrible” and “not fair and not honest”.

Trump administration says US ‘doesn’t need’ ICC after accusing court of unfairly targeting Americans for war crime charges

The United States was accused of launching “an assault” on the world’s legal order after imposing more sanctions on the international criminal court (ICC).

Unveiling the Trump administration’s latest escalation against the court, which it has accused of politicization and unfairly targeting Americans for war crime charges, Marco Rubio, the US secretary of state, declared: “Either the ICC will end its threats, or we will end the ICC.”

A proposal to livestream the killing of Nidal Hasan by firing squad opens a window ever wider to the Trump administration’s complete moral vacuity

More fool me! Here I was thinking nothing that America’s Trump administration could do or say, no matter how politically and morally bankrupt, no matter how venal or violent, was capable of shocking me any longer.

Then I woke to today’s news that one of the Trump cabinet’s bigger boofheads – the uber Christian nationalist, crusader-fantasist and “secretary of war” Pete Hegseth had announced that America would have a public firing squad execution of murderer Nidal Hasan.

In the shadow of the Parthenon, the secretary of state gave a selective reading of history as he urged Europe to ‘awaken from its slumber’

The US secretary of state, Marco Rubio, delivered a classically inspired apologia for Donald Trump’s “America first” foreign policy on Wednesday, giving a sweeping speech to the backdrop of the Parthenon in Athens that appeared tailor-made for campaign ads if he runs for president in 2028.

In the speech, the top US diplomat drew historical parallels from the founders, philosophers and conquerers of antiquity to the modern American spirit – as well as his family’s own journey to the United States – as he called on Europe to “awaken from its long slumber” and reject a “future of atrophy and servitude and decline”.

The US president has taken credit for far-right victories across Latin America, but those wins have had more to do with fears of gang crime than his meddling

Donald Trump has enjoyed very few foreign policy victories since returning to power. From failed wars to failed peace processes, his second term in office has been marked by one costly blunder on the world stage after another. In Latin America, though, the US president has a different story to tell.

His administration’s national security strategy outlined how the US wanted to “restore American preeminence in the Western Hemisphere”. It was a brazen document, laying out how his government would interfere in the political life of countries it considered part of its sphere of influence, rewarding governments and movements that are “broadly aligned with our principles and strategy”.
