# Trump has utterly changed the rules of engagement. World leaders must learn this – and quickly

It’s not only about Donald Trump. It’s not just about , or defeating Russia, or how to boost Europe’s security, or what to do about an America gone rogue. It’s about a world turned upside down – a dark, fretful, more dangerous place where treaties and laws are no longer respected, alliances are broken, trust is fungible, principles are negotiable and morality is a dirty word. It’s an ugly, disordered world of raw power, brute force, selfish arrogance, dodgy deals and brazen lies. It’s been coming for a while; the US president is its noisy harbinger.

Take the issues one at a time. Trump is a toxic symptom of the wider malaise. For sure, he is an extraordinarily malign, unfeeling and irresponsible man. He cares nothing for the people he leads, seeing them merely as an audience for his vulgar showmanship. His undeserved humiliation of Ukraine’s valiant leader, Volodymyr Zelenskyy, was, he crowed, “.” As president, Trump wields enormous power and influence. But Potus is not omnipotent. America’s vanquished Democrats are slowly finding their voice. Connecticut senator Chris Murphy shows how it should be done. Don’t bite your lip. Don’t play by rules Trump ignores. When Trump tried to  for January’s deadly Potomac midair collision, Murphy hit back fiercely.

“Everybody in this country should be outraged that Donald Trump is standing up on that podium and lying to you – deliberately lying to you,” . Trump was at it again when he mugged Zelenskyy last week. But it is not passing unchallenged. Street protests  and  followed. A campaign gathers pace to block Trump’s planned . Opinion polls show growing opposition.

It seems strange to talk about “resistance”, as if a Nazi-style wartime occupation is under way. Yet resisting Trump is what our leaders must do. The world’s most admired democracy is held hostage by a far-right clique of thugs and chancers. Its leader  and talks of a presidency for life.  and  raise stiff-armed salutes. European neofascists drool adulation from afar.

Ukraine, despite Trump’s betrayal, remains the epitome of resistance. The Ukrainian people are fighting for freedom, sovereignty and democratic self-determination. The issue is simple. Since the US cannot any longer be relied upon, Europe’s leaders know what they must do: supply more and better weapons for Kyiv, such as Taurus missiles; provide more humanitarian aid and finance, obtained by seizing ; and collectively raise their defence spending. From leaders such as Keir Starmer and Emmanuel Macron, we need less polite subservience and more .

To be effective, European leaders need to put concerted pressure on the US government to provide credible, long-term security guarantees for  and a backstop for any force that the UK and Europe deploy to monitor the ceasefire. It’s reasonable to expect the US to support a European peace initiative. If it does not, an open rupture with Washington should not be dodged. Equally, they need to put more pressure on Russia, too, to halt its daily slaughter and bombing in Ukraine’s cities. Putin could stop this war today – after all, he alone started it. The fact he refuses to do so is proof, if it were needed, of Zelenskyy’s contention that he cannot be trusted in anything he says. He must be squeezed further.

Right now, the opposite is happening. Military analysts warn that a gleeful Kremlin, encouraged by western discord, may step up its offensive in the east and try to capitalise on Ukraine’s demoralisation, perhaps even reinstating Putin’s original plan to seize the whole country. To deter such scenarios, EU leaders, meeting again in Brussels  after their London weekend talks, must finally bury their differences and draw a line.

Starmer says that he and Macron are now . Good. The leading European Nato powers should demand an immediate halt to all fighting in Ukraine and Kursk. They should launch a peace process inclusive of all interested parties, without preconditions or prior concessions. If Putin balks, they must withdraw their diplomats, close borders with Russia, move to interdict its exports, mobilise their armed forces – and set a deadline for providing defensive air cover for all unoccupied Ukrainian territory. Russia must be reminded that the west has teeth, too – and will, if forced, resist Putin’s unlawful aggression with everything it has got. Enough of Trump’s scaremongering nonsense about a third world war. Putin is a mass murderer, not a mad murderer. He’s also a coward.

Given Trump’s treachery and threats to cut military aid, only a strong, united Europe stands a chance of preventing Ukraine’s defeat on the battlefield. Were Ukraine forced to capitulate to a Kremlin deal and lose its sovereignty, it would set a disastrous precedent for free people everywhere, from Taiwan and Tibet to Moldova, Estonia,  and Greenland.

Marco Rubio, Trump’s obsequious secretary of state, spoke revealingly last month about his vision of a 21st-century world dominated by the US, Russia and China, and divided into 19th-century geopolitical . It was necessary to rebuild US relations with Moscow, Rubio argued, to maintain this imperious tripartite balance of power. This is the partitioned future that awaits if Trump’s surrender strategy prevails and he and Putin carve up Ukraine.

Such a global catastrophe was foretold. In his novel Nineteen Eighty-Four, George Orwell describes a nightmare world divvied up between three great empires or superstates, Oceania, Eurasia and Eastasia, which deliberately stoke unceasing hostilities. Their shared characteristics: totalitarianism, mass surveillance, repression, immorality, gross inhumanity. Sound familiar? Annalena Baerbock, foreign minister of Germany, a country that knows much about fascism, past and present, recently said that a “”. Ukrainians, under occupation, are only too familiar with the evil that has descended upon their heads. This is the violent, lawless dystopia towards which the Americans in the Oval Office are leading us. Unless they are stopped. Unless we fight. Unless Europe resists.
