Ukrainian President Volodymyr Zelensky criticized former U.S. President Donald Trump during a visit to the United Kingdom, accusing him of siding with Russian President Vladimir Putin and calling him “the wrong side of history.” Zelensky’s remarks came amid heightened tensions following Trump’s recent energy deal with Russia, which Kyiv and its allies have condemned.

During his trip, Zelensky met with British Prime Minister Andy Burnham, who expressed strong support for Ukraine. Burnham emphasized that Britain stands firmly behind Kyiv amid ongoing conflict. Zelensky also held a private audience with King Charles at Buckingham Palace, where he thanked the monarch for his unwavering backing of Ukraine in the face of Russian aggression.

In a television interview with Piers Morgan broadcast during his visit, Zelensky openly denounced Trump’s decision to purchase Russian diesel fuel in an effort to reduce U.S. energy costs. The former president also suggested Ukraine needed “a new leader.” Zelensky described these moves as a betrayal and lamented the loss of a powerful partner, underscoring the pain caused by Trump’s stance.

Zelensky compared Putin to Adolf Hitler, calling him “the Hitler of our time” and reaffirming Ukraine’s determination to resist Russian military pressure. Trump’s administration has faced criticism for attempting to broker an energy ceasefire, though Russian attacks on Ukraine’s power infrastructure have continued. Since halting strikes on Russian oil facilities, Ukraine has reportedly targeted key Russian internet data centers, including those belonging to Yandex.

Separately, Ukrainian officials reported difficulties with the Starlink satellite internet system provided by Elon Musk’s SpaceX. According to Ukrainian defense sources, the system restricted connectivity to drones and missiles traveling faster than 100 mph, effectively grounding some interceptor drones crucial to Ukraine’s air defense. The limitations were implemented without advance notice, prompting concerns about their impact on Kyiv’s ability to defend itself against Russian Shahed drones. A Ukrainian government aide described the move as partners depriving Ukraine of one of its vital defensive tools.

The developments highlight ongoing challenges for Ukraine as it seeks international support and advanced technology to counter Russian aggression, while navigating complex geopolitical dynamics involving allies and former leaders.
