U.S. President Donald Trump has a remarkable ability to be appear differently to different people. Like the Wizard of Oz, now he is a giant talking head, now a beautiful maiden, now a beast, now a ball of fire. The man behind these disguises is hard to pin down, and yet the fate of whole countries depends on what Trump really thinks — nowhere more so than in the case of Russia’s aggression against Ukraine. Trump’s latest pronouncement on the war in Ukraine was as enigmatic as ever. Writing on Truth Social on Sept. 23, Trump — who had previously called the war in Ukraine “Zelensky’s war” — declared that Kyiv “is in a position to fight and WIN all of Ukraine back in its original form,” and even suggested that the Ukrainians could push beyond the borders of 1991. “Good luck to all,” he added, in a twist that added very little clarity to his message. Yet the message was welcomed by those who have pinned their hopes on Trump coming around to support Ukraine. It was read as an indication of the U.S. president’s frustration with Vladimir Putin and a sign that perhaps his bromance with the Russian dictator was over. More careful observers doubt this interpretation. For instance, Polish Prime Minister Donald Tusk concluded that “behind this [Trump’s] surprising optimism lies a promise of reduced U.S. involvement and a shift of responsibility for ending the war to Europe.” “Better truth than illusions,” he added.

Seeing how Trump’s position on Ukraine has shifted in recent months, it is unwise to think that his latest pronouncement represents a new departure. It is already obvious that the United States has no real appetite for deep entanglement in Ukraine. The best that can be hoped for is that Washington will continue providing intelligence and military aid to Ukraine (as long as the Europeans are willing to foot the bill). It is Europe that now must step up by keeping Ukraine afloat and well supplied with weapons. It is Europe, too, that must live with the consequences of a prolonged war on the continent. The consequences are going to be dire. Ukraine has, of course, borne the brunt of the conflict. In addition to the terrible human toll of hundreds of thousands of casualties and millions of permanently displaced people, Ukraine has been devastated economically. A rapid recovery is not in the cards. As the war continues, the costs will continue to mount, dragging the country to the brink of insolvency and perhaps an outright collapse. Russia, too, has been battered by the war. Suffering from high inflation, prohibitive interest rates, a growing budget deficit, labor shortage and unsustainable military spending, Russia’s economy is a slow train wreck. The prospects are getting worse with every month of fighting. If Russia loses the war, it will likely succumb to chaos and fragmentation. If it wins, an authoritarian, broken Russia will have to bear the prohibitive political and economic costs of the reconstruction of Ukraine.
